Continuity on new paths Dear reader, the tragic events in the U.S. Of 11. The events of September last year will remain in our memories for a long time to come and it will take time to come to terms with them. They have changed the world – the private as well as the public and corporate world. Despite these difficult times, we will continuously and consistently implement our strategic goals, such as the worldwide expansion of our sales and service network, and assert ourselves as an independent company. After 28 years of chairmanship of the Supervisory Board, Mr. Rolf Sandvoss has decided not to run for this office again and to appoint as his successor Mr. Rechtsanwalt Dr. Hensel, a long-time, younger colleague on the Supervisory Board. At the last Annual Stockholders' Meeting, Dr. Hensel unanimously elected chairman. This ensures that the philosophy of SAMSON AG will be maintained on its future path: tradition-conscious, competent and international. Mr. Sandvoss will not be lost to SAMSON AG as one of its important business personalities; he will continue his 36 years of service on the Supervisory Board. He has already been able to accompany three generations of board members;

Under his chairmanship, the company's balance sheet total has increased more than tenfold. His special interest in our French subsidiary. This evolved into the most important distribution-. Manufacturing plant outside Frankfurt. Another example of a successful combination of tradition consciousness. Modern thinking we would like to present to you in this magazine. The city of Barcelona is an important European business metropolis and a link between the Iberian Peninsula and Western European culture. At the same time, the people of this city fascinate with their self-confident adherence to their Catalan tradition. This makes the city one of the most diverse, exciting and dynamic on the Iberian Peninsula and an ideal location for our branch office. We hope you enjoy reading this issue of

Innovations

Expert knowledge from afar

The doctor goes the distance The progressive development in information and communication technology not only influences office and administrative processes. Even fields as fundamentally different as medicine and process technology can benefit from global networking. On closer inspection, however, one soon realizes that despite all their differences, their goals and requirements do have some things in common. Because whether it's man or machine, when it comes to complaints, you should rely on expert knowledge. SAMSON launches its TROVIS-EXPERT diagnostic program.

Operation Lindbergh in September 2001, a procedure carried out entirely by telesurgery. Although 7.While the surgeon and patient are separated by a distance of only 000 km, the surgeon in New York can see and control the movements of the robotic arms in Strasbourg on his screen almost simultaneously – for the first time in the history of medicine.

In the Australian outback and on the high seas, remote medical diagnosis is vital for survival. On the Gorch Fock, the wastewater treatment plant is controlled by maintenance technicians on the mainland via the Internet, regardless of which of the world's oceans the training ship is sailing at the moment.

Remote diagnosis in medicine and technology Dr. Everywhere – A visit to the doctor: impossible in many parts of the world, namely when the nearest doctor is hundreds of kilometers away. However, if the doctor is only needed for the diagnosis, while the treatment can also be performed by laymen, a video transmission between the patient and the doctor, if necessary, can be used. With the support of a medically trained helper on site, replace the conventional examination. With the possibilities offered by mobile communications, however, remote diagnosis as an aspect of "telemedicine" is taking on a completely new quality: bodily functions such as the heartbeat can be continuously measured and transmitted to the doctor, who thus has an overview of the state of health of a high-risk patient at all times. Visions of comprehensive medical monitoring already exist for the future, even through implants in the body. Pioneers – Telemedicine is no longer limited to purely diagnostic purposes. With the help of robots, even operations can be carried out from a distance, even over thousands of kilometers. Most spectacular case to date: a transatlantic operation last year. A robot in Strasbourg, controlled by a surgeon in New York, removed a patient's gall bladder. The symbolic name of this premiere: "Operation Lindbergh" – after the pilot who, three quarters of a century earlier, was also the first to overcome the obstacle of the Atlantic in a non-stop flight. Tele-customer service – No one is seriously thinking of having robots perform repairs on control valves, for example, in a similar way. But here, too, video transmission would offer a perspective for diagnosis and clues

For troubleshooting, so that in addition to the experience of customer service personnel, developer know-how can also be called upon when needed. Suitable "helpers" on site, however, can provide even more meaningful data: For control valves, for example, the electronics of SAMSON's HART positioner in combination with TROVIS-EXPERT software enables wear prediction and diagnosis for preventive maintenance. But the increasing use of electronics also affects the core functions of the field devices. Despite convenient user interfaces such as TROVIS-VIEW, this constantly growing variety of functions now overwhelms some users. Unsatisfactory function is therefore increasingly the result of faulty settings. However, such errors could be corrected remotely with little effort, provided that the customer had direct access to the field device, e.G. Via the Internet. Safety – but process plants harbor a high risk potential in the event of manipulation. For this reason, plant operators are extremely skeptical about access from the outside – for fear of unauthorized access via the diagnostic interface. Direct access to device data via the Internet while the plant is running will therefore not be possible in the foreseeable future in process technology, in contrast to building technology with its lower security requirements. In the less problematic workshop environment, on the other hand, remote diagnosis and conﬁguration have a real chance – not to replace the expertise available there, but to supplement it. Customer service would become faster and more efﬁcient – an advantage for both manufacturer and customer. Medieval looking alleys. Stores make strolling around old Barcelona a pleasure. For almost seven decades, SAMSON has been supplying the Spanish industry with high-quality products. Has contributed to the high reputation of German manufacturers on the Iberian Peninsula. After the renowned Faust y Kammann trading company had initially been responsible for distributing the products for many years, SAMSON founded its own subsidiary based in Barcelona, Spain's economic metropolis, exactly 20 years ago in 1982. 2002 is a year to celebrate. But not only SAMSON has a round birthday: Antoni Gaudí would have turned 150 this year. And so the year 2002 was declared the Gaudí Year in Barcelona in memory of the Catalan master architect.

The spire of Casa Battlo: the house, built by Gaudí between 1905 and 1907, like all his buildings, has hardly any corners or edges.

The Casa Milà is Gaudí's last great "bourgeois" building, built before he devoted all his time to the construction of the Sagrada Família.

Barcelona – Too bad for a ﬂüchtiges adventure love at second sight – One will not fall in love with this city immediately, but very slowly develop its affection. This, however, makes the connection more intense and lasting. Cervantes enthusiastically tells his chivalrous Don Quixote about Barcelona: "A place of good breeding, a hostel for strangers, a shelter for the poor, a home for the brave, a refuge for the reviled, and a place of loyal friendships, unparalleled in its location and beauty." A city with style – In the period between 1880 and 1910, the city achieved world fame with the "Modernisme", which was called Jugendstil in Germany and Art Nouveau in France. In Barcelona, this style found its unmistakable Catalan expression through architects such as Antoni Gaudí (1852-1926). His incomparable works of art are what make Barcelona truly unique. In 1984, UNESCO declared some of them, such as Park Güell and Casa Milà, a World Heritage Site. Gaudí succeeded in creating stones with soul. Its houses breathe. The Sagrada Família, Gaudí's unfinished church of atonement, is probably the city's best-known monument and Europe's most curious church construction site. In 2002, in commemoration of the 150th anniversary of the. Birthday of the master architect on the occasion of the "Gaudí Year" in Barcelona. Opportunity to visit the city and participate in one of the many special events, e.G. B. Attending one of the concerts on the roof terrace of the "Pedrera" on the Paseo de Gracia at night in summer. The lifeblood of the city – The Rambla, that's 1.200 meters of joie de vivre. On it the way is the goal. The promenade, which actually consists of five rambles, stretches from Plaza Catalunya to the Columbus Monument at the harbor. This is where

Everything. The fascination lies in the juxtaposition and coexistence of different tastes and cultures in such a confined space. A Babylonian babble of languages, strolling and looking around with side shows worth seeing, such as the Boqueria, the colorful fruit and vegetable market, or the Plaça Reial, one of the most beautiful squares in Barcelona. The city is a conglomerate of art, culture and cuisine. One of the most enjoyable neighborhoods is the "Barri Gòtic. The adjacent district of La Ribera. Here you ﬁnd everything combined in a very small space. Art, culture and cuisine – An absolute must, the Museo Pablo Picasso: On the way to the museum, one easily feels transported back to the Middle Ages. Narrow alleys and enchanted backyards characterize the image of the city district. The museum itself is beﬁnd in a grand medieval noble house. After all 2.200 works make up Picasso's life's work, some of the most important are exhibited here.

"I wanted to be a painter and I became Picasso." – The city has produced many famous daughters and sons. SAMSON MAGAZINE

The Sardana, the national dance of the Catalans, is an expression of their solidarity and the Catalan soul. Dancing in circles.

Right. Left, right. Left, right. Then the rhythm accelerates, the arms at first firmly attached to the body, go up easily. Finally, the dancers, hands above their heads, take quick intricate steps and get into a wonderful swaying motion to the sounds of the Copla chapel. It takes about eight minutes for a dance to take place, in which complete strangers gather in squares, for example in front of the cathedral on Sundays, and simply dance around a mountain of their discarded bags, jackets and coats, exuding an eerie peaceful atmosphere."

Although Pablo Picasso was born in Málaga and pitched his tents in Paris, he spent decisive years in Catalonia's capital, which thanked him with a stately museum. He, Dalí, Miro and Tàpies left behind more than colorful dots. Its Einﬂuss has turned Barcelona into a center of art. Famous daughters, famous sons Not far away we come across the Palau de la Música, a modernist building designed in 1908 by Lluis 8 SAMSON

Domenech i Montaner built. In this extraordinary temple of music with excellent acoustics, you can admire famous Catalan opera singers such as Montserrat Caballé or José Carreras on stage. Sardana, expression of the Catalan soul – James A. Mitchener describes the dance: "Like a living clock that runs in both directions, the dancers, who form a circle, slowly take a few steps to the left and then to the right

Symbiosis of nature and sound – The Montaña de Montserrat is located to the west of Barcelona. The mountains can be seen from far away. Mystically they rise out of the hilly landscape, the plain of the Baix Llobregat. As if the gods had folded their hands in prayer here ages ago, brown bare rock lines up mountain after mountain in quiet, peculiar beauty. It is always worth a climb, whether by car on the winding panoramic road, by cable car built by German engineers at the beginning of the last century, or on foot for the athletic hiker.

The people of Barcelona are particularly proud of their local mountain, Montjuïc. It is home to many of the facilities used for the 1992 Olympic Games, including the Palau Sant Jordi.

At an altitude of 725 meters, they all meet the Benedictine monastery in an incomparable location that probably inspired Wagner to write his Parsifal. Montserrat is the home and spiritual center of Catalanism: Every day, numerous visitors make a pilgrimage here to see the "Moreneta," the black Madonna, the patron saint of Catalonia. The boys' choir of the monastery has achieved world fame, and it is an incomparable experience to hear the beautiful voices at noon during the "Salve Regina" or in the evening during the "Virolai" in honor of the patron saint. Not only is the soul taken care of – so much art and culture also makes you hungry. Catalan cuisine is as idiosyncratic as the country itself. One has often looked into the pot of the neighbor France, but never lost its own style. Even the most famous gourmet restaurants, more inclined to French cuisine culture, can not afford to be completely at the Catalan

Whether within the city of Barcelona itself or outside in the mountains of Montserrat – there is always plenty to discover.

Passing taste. You will ﬁnd at least some of the country's dishes everywhere, be it a "souquet de peix a la catalana" (fish stew) or the national dessert "crema catalana" (egg custard with a crispy layer of caramelized sugar). If a complete dinner is too much for you, you will find a rich offer of "tapas" in one of the many xampanyerías in the Santa Maria del Mar district, small delicacies on a slice of bread that used to be placed on top of the glass of wine – tapar! For those who have partied all night, a breakfast of "churros con chocolate" is offered. It is hard to think of a breakfast more difficult to digest, but neither could there be a better one. A people who can stand churros and chocolate for breakfast need no other proof of their courage!

The Montserrat Monastery, nestled in the Montaña de Montserrat, is home to the Black Madonna, the patron saint of Catalonia. SAMSON MAGAZINE

The SAMSON team in Rubí around Branch Manager Ulrich Rohlfs (3. V. R.)

A successful partnership A city made for SAMSON – Catalonia goes its own way. And so Barcelona seems to be a city made for SAMSON. At SAMSON, too, it ﬁnds itself, this special mixture of continuity and reliability, but also modern thinking and innovative strength. At the turn of the millennium, the subsidiary moved into a newly built, fully air-conditioned logistics and service center on the outskirts of Barcelona in Rubí, over 3.000 square meters of Grundﬂäche. The new branch office is perfectly tailored to the needs of SAMSON AG. For example, the office building was equipped with spacious seminar rooms for employee and customer training courses. The functional workshop equipped with state-of-the-art equipment as well as the high storage capacities make it possible for SAMSON's-

This will enable us to respond directly and on site to almost all customer requirements: All common spare parts are in stock and, according to individual needs, complete control valves can be assembled and directly checked for tightness and proper functioning. Close cooperation between the logistics center, conveniently located near Barcelona airport, and the field offices in Santander, Madrid, and Lisbon and Porto in Portugal has enabled SAMSON to install a ﬂextremely ﬂexible after-sales service despite the vastness of the country. Within 24 hours, both the numerous small cheese dairies in the north and the large chemical companies in the south of the peninsula can be served. The establishment of a further field office in Cádiz is a priority objective

Thanks to the high storage capacities, almost all customer requirements can be met directly and on site within 24 hours.

For the year 2002. The former Gades is considered the oldest city in Europe. Founded in 1100 B.C. By the Phoenicians, it became the largest and most important trading center along the Mediterranean coast just 300 years later. Above all, the chemical, sugar, and food industries located in Andalusia, including the large olive oil producers, will then be served by the engineers of SAMSON's Cádiz office. The fact that the Andalusian province of Jaén, with 50 million olive trees, also brought to the peninsula by the Phoenicians, has more olive trees than the rest of the EU including Turkey, dates back to the Reconquista. In the course of the reconquest, the Muslims were pushed further and further south and developed the sophisticated irrigation technology that is still proﬁted in many places today. Friendship for life – What remains to be done now? Once again back to Barcelona on the Rambla. The upper section, the Rambla de Caneletes, is home to the Caneletes fountain. Those who drink from its waters always return to Barcelona – so the saying goes.

The entrance to SAMSON AG's new logistics center in Barcelona: At 17. November 2000 was celebrated inauguration.

Repsol YPF's Rafﬁnerie in Tarragona meets the latest environmental standards. Repsol – Fiesta of success Through the merger of several state-owned energy-. Chemical company, Repsol, Spain's largest industrial group, was founded in 1987. Its production focuses include a wide variety of fuels. For this purpose, the company operates its own service station networks in Spain under the Repsol, Campsa and Petronor brands. Repsol also supplies aviation kerosene to all airports on the Spanish mainland and in the Balearic and Canary Islands. Repsol is also present in the gas business with Spain's leading natural gas company Gas Natural. Other products include a wide variety of oils and lubricants, chemicals, hydraulicﬂuids, fuel oils, propane gas, base materials for paints and varnishes, coatings, insulating materials, waxes and parafﬁnes. In addition to its stake in the Argentine energy supplier Astra, in 1999 the Spaniards took over the largest Latin American energy supplier and petrochemical specialist, Argentina's YPF S.A. The new company, Repsol YPF, has a daily production of 945 barrels per day.000 barrels the seventh largest oil and gas company in the world. By the year 2005, the production volume is to be increased to 1.3 million olives. Barrels are ramped up. SAMSON is also part of the success. For example, in cracking, the quench oil circuit, which is used to cool the raw gas before it enters the first distillation column, is controlled with ceramic-lined VETEC rotary plug valves. Due to the process, the quench oil is loaded with coal particles and other solids and has an extremely abrasive effect. Nevertheless, the service life of VETEC valves is three years, not least due to the close cooperation between Repsol YPF, VETEC and SAMSON Spain. The previously used product had a service life of less than three weeks. SAMSON MAGAZINE

Entrepreneurship on the right course

Porto – the city in northern Portugal gave its name to the country and to port wine. The Café Majestic is one of the most beautiful cafés in the world. Has already won several awards.

Portuguese sailors, under Prince Henry the Navigator (1394-1460), were the first Europeans to sail and explore the world's oceans. Henry's captains discovered and settled the Azores and Madeira. They were on their way on the caravel he had developed, a type of ship that was almost revolutionary for its maneuverability at the time. A few decades later, Bartolomeu Dias explored the west coast of Africa and reached the Cape of Good Hope. Vasco da Gama finally circumnavigated the Cape. Arrived in Calicut, India, in 1498. Finally, a sea route to India was found – the lucrative spice trade had long been tempting. On 21. April 1500 finally Pedro Álvares Cabral reached the Brazilian coast. SAMSON is also on the right course in Portugal, proﬁtting from both the currently expanding automotive industry and the cellulose furnace industry, which has been growing for years. For example, Portucel, operator of the largest eucalyptus mill in Europe and one of the largest producers of pulp anywhere, is one of the company's customers.

Prince Henry the Navigator is regarded as the father of seafaring and navigation. In 1415, he founded his famous maritime school in Sagres.

Many companies are reprivatized; the industrial sector, neglected until the democratization of the country, grows continuously. The small country became one of the largest pulp producers in the world. Today, it is once again engaged in considerable foreign trade. SAMSON decided to grow with the company: In 1991, the Spanish subsidiary opened a branch office in Lisbon, followed later by another office in Porto. This was a response to the growing needs of Portuguese industry. In addition, the distances on the Iberian Peninsula have once again become shorter. As both offices work closely with their Spanish partner offices, it is possible to operate with a high degree of ﬂexibility across the whole country. Entrepreneurial spirit just keeps paying off.

The Moorish invasion brought azulejaria, the Arabic craft of decorating walls and facades in the most imaginative way with glazed tiles, all the way to Portugal. In the centuries that followed, azulejos, almost ubiquitous, told of the history and fate of the country and its people in ever more magnificent and impressive ways.

When electricity changes color

Parabolic trough collectors on the "Plataforma Solar de Almería": They concentrate solar rays directly onto a … Apocalyptic scenarios such as the overﬂutting of coastal regions. Whole groups of islands as well as a shift in climate zones as a result of global warming are considered probable. Reality is already the UV, ozone and smog alarms in many industrialized countries. The problem of steadily increasing world energy consumption is brought home to us almost daily. Up to 300 mirrors follow the course of the sun in Almería, Spain. Focusing their rays on the CESA I tower: In the solar tower power plant, electricity is generated from sunlight.

14 SAMSON

… Pipeline in which water is heated. SAMSON control valves regulate the flow rate. Subsequently, turbines are used to generate electricity with a considerable degree of efficiency. Generators produce electricity – sunny prospects!

Full solar power ahead Conventional energy generation – At present, energy is generated primarily by conventional means from the increasingly scarce fossil fuels oil, gas and coal, or from uranium. The former are responsible for the high CO2 emissions. The associated global warming. Nuclear energy is considered to be clean and technically controllable, however, it represents a risk factor that is difficult to calculate due to the unresolved issue of final storage and the terrorist threat. Alternatives are urgently needed. Alternative sun – The use of solar energy, which reaches us every day, has long been on the wish list of technicians and engineers. The center of our planetary system represents an almost infinite source of energy. Every day, far more energy in the form of short-wave light radiates onto the earth than we need – free of charge. Only like the solar energy transform, store, distribute and use? Photovoltaics, the direct conversion of sunlight into electrical energy using the photoelectric effect, is already being applied in a variety of ways. Despite intensive research work, however, their efficiency is only 6 – 12 %. Power generation with parabolic trough collectors could be the magic formula. These solar collectors are used to produce superheated steam that drives generators. SAMSON is right in the middle of such sophisticated steam controls. Full of sun – In the south of Andalusia, in Tabernas, Spain's furnace and Europe's only desert region, a group of German and Spanish scientists is researching the new technology. Europe's largest solar energy research station, the Plataforma Solar de Almería, is located here. It is the only plant in the world in which the generation-

Gation of high-pressure steam using parabolic trough collectors is being investigated. Futuristic in a barren environment – The collector field consists of a 550-meter-long row of parabolic mirrors that concentrate the sun's rays 80-fold directly onto a pipeline. In it water is heated to superheated steam. The flow rate is controlled by SAMSON control valves, which is no easy task with a maximum outlet temperature of 400 °C and pressures up to 100 bar. The efficiency achieved is remarkable in comparison with photovoltaics: it is currently just under 20%. A tower made of sunlight – Promising in terms of efficiency, electricity generation in a solar tower power plant could also be something the team is also researching. The concrete tower, which stands like a conductor in front of his orchestra, measures 83 meters. Computer-controlled, the approximately 300 mirrors, the heliostats, follow the course of the sun, direct the captured rays directly onto an absorber at the top of the tower and heat it to more than 1.000 °C on. It is cooled with ﬂuid sodium. The energy stored in the sodium is then used to generate electricity conservatively via the steam rail. An efficiency of 23% has already been achieved, but the plant is still very expensive. Alternatives to be used – The advantage of using solar thermal energy is obvious: emission-free power generation with almost unlimited availability. What fossil fuel can compete with this?? Maybe soon you'll be driving across Europe to Andalusia with sun in your tank. SAMSON MAGAZINE

Specialist topic In Lienz, people are investing in the future: local wood, sawdust and solar energy provide heat and electricity.

Natural heating – high production costs and the dependence of solar thermal plants on direct sunlight make the search for other alternatives sensible. So just heat and move around with oil or coal? There are more environmentally friendly options: renewable raw materials. Biomass, as it is known, is in a sense stored solar energy: via photosynthesis, Pﬂanzen thrive and thus provide fuel such as wood, straw or even Pﬂanzenöle (plant oils). Using the energy-rich sunlight, the Pﬂanzen convert exactly as much CO2 into carbon and oxygen as is produced when they are burned – a clean balance sheet. 16 SAMSON

Since the 16. Rapeseed was cultivated in the nineteenth century, initially for the production of lamp oil. Today it is one of the world's most important crops.

The sun shines in Lienz at over 2.000 hours a year – more than enough to power a solar system.

The fuel quality of biomass is subject to fluctuations, but a new control concept has improved the annual utilization rate.

Energy from biomass In the forest, that's where the power grows – Whether wood or straw, bark or pressed sawdust, these energy sources have one thing in common: they grow back quickly or are used for energy generation. Waste from the industrial processing of wood. The classic biomass consists of wood waste from sawmills and forests. But wheat, rye or barley are also well suited and quickly available as annual crops. Like sawdust, they are pressed into shape, so-called pellets. Stadtwärme Lienz – A combined heat and power plant in Lienz (Austria) has been operated with biomass since autumn 2001. The city is supplied with district heating all year round from renewable energy sources such as sawdust, wood chips and bark. The district heating network is being steadily expanded and will reach a network length of 37.5 km in 2003. SAMSON provides the entire technology for the nearly 1.000 district heating stations. The plant will supply heat quantities of 60 GWh per year. In addition, there is a solar plant with 630 square meters of collectorﬂäche. Lienz is the perfect place for this-

The use of domestic, renewable energy sources promotes forest management.

Lienz is virtually spoiled by the sun, so that an additional 250 MWh of solar energy can be "harvested" per year. Liquid alternatives – Running a car on wood is certainly not up to date. But biomass is also available in ﬂüssig form: Ethanol can be obtained from sugar beet and sorghum. Or rapeseed: the high-yielding Pﬂanze provides cold-pressed oil that can be used directly as fuel for diesel engines. These only need to be slightly modiﬁed due to the higher viscosity of the oil. If the glycerol is removed from the plant oil by transesterification and replaced by methanol, the well-known biodiesel is produced. A practical side effect: the glycerine produced ﬁnds grateful customers in the cosmetics industry. Until now, glycerin could only be obtained from natural gas. A clean thing – Since rapeseed is easy to grow and also thrives in industrialized countries where the diesel is needed, the cost of transport is eliminated. In addition, the processing effort is lower. The combustion of biodiesel in modern engines also produces significantly fewer toxic exhaust gases than the use of conventional diesel fuel. Biodiesel is naturally sulfur-free, whereas a lot of energy has to be used to desulfurize the fuels used so far. Energy to the hilt? Biodiesel is currently used in Germany at around 1.000 service stations offered. Taking into account site suitability and crop rotation conditions, about 6 % of the diesel fuel demand in Germany could be covered by biodiesel. Biodiesel can therefore not be seen as a substitute for petroleum, but as a supplement to it. After all, every drop is a little piece of sunlight. SAMSON MAGAZINE

Impulses

The positioner experience

Skepticism among visitors: Under water, too? The experiment illustrates the low air consumption of the positioner.

Try it out and join in

Do you feel the same way? You are at a trade show, have your sights set on your goal, and want to find out about certain products as effectively as possible. Deadlines are pressing, routes are longer than expected and a flood of technical information awaits them at their destination. The details weigh heavily and it is hard to grasp essentials quickly. But not only that. Back in the hotel room or on the train, the memory is often already faded. But how do you manage to cope with the informationﬂut?? SAMSON has thought about this and is taking a new approach with its trade show concept "World of Experience".

SAMSON's Type 241 Control Valve stands up even to hostile environments.

18 SAMSON

Even an egg remains intact: SAMSON control valves handle products very sensitively. The competition with the machine to see who can position faster. Precise positioning of a butterfly valve requires a lot of skill.

SAMSON – A different kind of product experience "Man versus machine", "Holy cow" or "It's possible under water", the three models in the world of experience invite visitors to touch them and try them out. Deliberately detached from the usual field of application in the plant and confronted with demanding tasks, the quality of SAMSON positioners is demonstrated in an unusual way, but all the more clearly and sustainably for it. Even at the trade show, you can find out what it means for a valve to have to control quickly, accurately, without overshooting, and with low energy consumption even under special requirements and the most adverse conditions. Competing with SAMSON technology – The "man versus machine – who positions faster" contest?" Is difficult to win. Two pushbuttons can be used to control the Type 3730 Positioner in a race against each other. The goal is to precisely position the SAMSON butterfly valve using the air supply and exhaust of the actuator. The specified set point must be reached as quickly as possible. It leaves a lasting impression how much skill it takes to compete with SAMSON technology. Very sensitive – SAMSON control valves with a 7-ton pneumatic actuator work so finely and precisely that they can easily leave their mark on an egg without any risk even with a large hysteresis. A non-contact rangefinder determines the distance to the Eioberﬂäche. Reports it as a set point to the SAMSON positioner. This positions the control valve quickly, without overshooting, and so precisely that no egg breaks during stamping. It's hard to imagine that one's own product is also controlled with the same instinctive feeling. And this from an actuator strong enough to lift full-grown elephants.

A valve in the endurance test – Of course, no procedure requires a valve to work under water. If a normal standard valve can nevertheless hold its own in this technophobic environment, it shows its quality in a very impressive way. Which valve is tight? The SAMSON Type 241 Control Valve with integrated positioner is it: Due to the low air consumption of the flapper-nozzle system, there is a slight overpressure in the positioner at all times, which reliably prevents the ingress of water and the possibly aggressive atmosphere. The spring chamber is also purged with instrument air; an additional protection against corrosion. So the longevity of the actuator is guaranteed here as well. The use of a solar panel also illustrates the very low energy consumption of the positioner: 4 mA is sufficient. Fast, accurate and durable – The new trade show concept quickly conveys what this means: impressively, vividly and for the long term. Sometimes it takes more than just collecting data to get informed.

Facts and figures

Type 241 Control Valve

A powerful type, compactly built With over 500.000 units sold, SAMSON's Series 241 Control Valve is the most successful on the global market. The fact that more than 15 % of SAMSON's control valves are currently supplied as JIS or ANSI versions underlines their worldwide acceptance. The Type 241 Control Valve, introduced in 1968, is characterized by its compact design, which was mainly achieved by the completely new and groundbreaking actuator concept at the time. Instead of a central spring, SAMSON's engineers used several internal springs or spring assemblies arranged rotationally symmetrically around the actuator stem. Also new and groundbreaking was the maintenance-free self-adjusting stuffing box packing: the usual stuffing box gland was entﬁel and the valve bonnet became lower. Another new product on the European market was the seat-guided V-port plug, which replaced the parabolic plug in 1975, which was susceptible to vibrations in larger seat bores.

Flow divider and throttle silencer ensure low noise levels during gas expansion.

V-port plug and bellows seals guarantee trouble-free operation. Integrated SAMSON positioners are essential for the function of the valve. Performance of the Type 241 is of decisive importance.

The best-known brand in the industry Uncompromisingly modular – The secret of the 241 Series' success lies in its modular design. The same valve bonnet is used within three nominal size groups. The inner trims can be exchanged for each other. The same packing is used for nominal sizes 15-80. The standard plug can be retained when retrofitting a bellows seal or an insulating section. All valves in the series can be equipped with actuator sizes from 120 to 700 cm2. The actuators are also modular. The 700 cm2 actuator can be equipped with 3 to 18 springs as standard. With only five different springs, this results in seven different spring ranges. The direction of action of all actuators can be reversed without special tools by using the same components. Up to date – Although the Series 241 control valve is already 34 years old, it is still considered to be one of the most modern today thanks to the continuous development of its design and production technology. The introduction of forged bonnets and housings in 1987, ANSI versions in 1988 and JIS versions in 1996 are just a few of the milestones in development. One of the decisive factors for the quality advantage of the Type 241 was the change in production process. Until 1989, the valve parts were manufactured on two rotary table machines with eight machining stations. Since then, they have been completely machined on modern machining centers in a single clamping operation. Misalignment and misalignment errors are eliminated. SAMSON's high vertical range of manufacture – bellows, diaphragms and attachments are produced in-house – also contributes to the all-round quality of the Type 241 Positioner.

No wish remains unfulfilled – In its current form, the Type 241 presents itself as a control valve for the medium pressure range that leaves nothing to be desired. Armored liners or cones of Stellite give erosive media no chance; faltering media is countered with a heating jacket. The bellows design easily meets even the highest requirements for external tightness. Flow dividers ensure low noise levels; cavitation problems are avoided with the AC trim. The positioner can also be integrated to save costs. With pressure relief, even small actuators can handle high pressures and – last but not least – the pneumatic actuators are also available in stainless steel for particularly high corrosion resistance requirements. 500.000 – a proud number. Behind it lies the success of a brand that is unique. With its strong sales network, SAMSON ensures worldwide service – around the valve, around the clock.

Heating jackets enable use with stagnant media – Safety shut-off devices for gas burners can be implemented cost-effectively. SAMSON MAGAZINE

SAMSOMATIC – good for animals

A South Indian rusty cat on the move in its new enclosure: the nocturnal small animal hunters are the runts among the wild cats.

What cats prefer For the first time since the Grzimek House in 1978, Frankfurt Zoo has reopened a large animal house. On almost 3.000 square meters stretches the cat jungle Southeast Asia, a huge facility with indoor and outdoorﬂächen, the natural habitat of the animals as authentically as possible emulated. Since July of last year, predatory cats that are threatened with extinction in their native countries have been able to live here in a manner appropriate to their species. Under the direction of Dr. Bernhard Grzimek (1945-1974), the Frankfurt Zoo, one of the oldest in the world, became synonymous with modern animal husbandry. The new big cat enclosure puts it back on the fast track in the international zoo business. SAMSOMATIC, a subsidiary of SAMSON AG, has contributed to the.

Since 1984, the Gesellschaftshaus of the Frankfurt Zoo has been a cultural monument, the entire complex with enclosures is a garden monument.

Even in the jungle it's getting cozy Regulated comfort – Making the animals feel really comfortable requires customized building technology equipment with a sophisticated control system. This must be able to integrate numerous special functions and react highly ﬂexibly to changed specifications; standard controllers are not sufficient for this purpose. If, for example, one of the three Indian lions Kashi, Kiri and Devika is to be able to laze around in the recreated monsoon dry area of northern India in true lion fashion, the sandstone rocks must have the right temperature – a lyingﬂächentemperierung with underfloor heating and sensors in the rocks is necessary. A rainforest was built for the nine South Indian rusty cats, which weigh only 1.5 kilograms and are the smallest big cats in the world, as well as for the pair of sumatran tigers: with waterfalls and pools, slightly damp-smelling bark mulch, many bamboo plants and trunks to climb on. When Sumatran Iban is on the prowl or the rainforest becomes too dry, a motion detector or sensors control the fogging system. A lot of work for the bio-designer – The seven-meter-high rainforest tree, an artificial trunk with real Pﬂanzenbewuchs, is incidentally intended as a romping place for the Southeast Asian clouded leopards, which are also to move into their own enclosure in the jungle in early summer 2002. "Macan dahan" – "branch leopard" is what the Indonesians call the climbing artists who prefer to hunt monkeys. Their short and muscular legs allow them to jump even five-meter-wide gaps in the branches of the trees when hunting. The enclosure is currently still a workshop: A BioDesigner is working on the final shape of the Stam-

Mes. It will be equipped with heating panels to provide the felines with cozy warm resting places even on the tree. TROVIS makes it possible – Two and a half years were spent building the cats' new habitat. The company is proud of the TROVIS MODULON control and automation system from SAMSON, a freely programmable DDC (Direct Digital Control) and autonomous automation station that integrates the various sensors and actuators on site and manages the information flow to the control station. Pﬂeger can conveniently and safely monitor what's happening in the enclosures via the fully graﬁsche TROVIS process visualization system – the images are tailored to the enclosure in question. Offspring wanted – With so much comfort it is only probable that sooner or later there will be offspring. The conservation program has also provided for this and has designed special litter boxes where the mother cats can retreat to raise their kittens.

Sumatratiger Iban is still alone on the prowl. Soon a female will join him.
