Booth number 4Q12

SAMSON manufactures globe and butterfly valves and self-operated regulators for all areas of process engineering. Controllers and automated systems round off our product line.

About us

SAMSON AG, a European market leader in control valves for industrial processes, has been successful in instrumentation and controls for over 100 years. Numerous inventions and innovative solutions guarantee SAMSON’s constant growth and on-going success. Outstanding inventions include the metal bellows as a reliable dynamic seal and integral positioner attachment for increased reliability and safety.

SAMSON manufactures control and butterfly valves in all commonly used materials according to DIN, ANSI, and JIS. The control valves are suitable for use in all areas of process engineering. SAMSON also manufactures self operated regulators for simple control systems with a constant reference variable. Sophisticated transmitters, controllers, and automated systems round off our product line.

Moreover, SAMSON and its subsidiaries – AIR TORQUE, CERA SYSTEM, KT-ELEKTRONIK, LEUSCH, RINGO VÁLVULAS, PFEIFFER, SED, STARLINE, and VETEC – provide tailor-made solutions for special requirements.

News & Innovations

Energy-efficient Valve for Cryogenic Applications

The new Type 3598 Cryogenic Valve was specially developed to meet the requirements of cryogenic applications. The valve is available in sizes up to NPS 8 and pressure ratings up to Class 900 and is suitable for temperatures down to –196 °C. The valve is optimized to handle high pressure drops. It has a cryogenic extension bonnet and circulation inhibitor that ensure a perfect temperature distribution and minimize energy loss to the atmosphere. The top-entry design facilitates work on the valve: the valve can be serviced without having to remove the enclosure or insulation it is installed in. The valve seat, piston and circulation inhibitor can be accessed directly after removing the actuator.

Lower actuator thrusts and smaller actuator sizes can be used thanks to the standard pressure balancing by a piston. This allows customers to save money on initial investment and reduce the cost of installation and servicing over the actuator’s life cycle. Possible fields of applications for SAMSON’s high-pressure cryogenic valve include air separation units (ASU) and marine applications, for example to store and transport cryogenic gases on LNG carriers.

With the Type 3598 Cryogenic Valve, SAMSON is responding to the customers’ growing demand for increasingly larger units. Further additions to the modular design, e.g. larger valve sizes and higher pressure ratings, are being planned.

Over the past 112 years, SAMSON has been driving forward new developments and introducing market innovations. Today, SAMSON is a worldwide leader in the manufacture of expertly engineered control valves and accessories for all industrial processes.

New Generation of Series 3730 Positioners

SAMSON introduces two new positioners from the Series 3730 – TROVIS 3730-1 and TROVIS 3730 3 – at the 2018 VALVE WORLD EXPO. The new positioners for 4 to 20 mA applications combine the latest technological developments with the proven device base known from the Type 3730-1 and Type 3730-3 predecessor models. Both positioners are particularly rugged thanks to their no-wear, non-contact travel sensing system. Two inductive limit contacts are available to reliably indicate both valve end positions. At the same time, the positioners’ air consumption has been reduced considerably by upgrading the pneumatics block. Operation continues to rely on the rotary pushbutton taken over from the successful Series 3730. TROVIS 3730-3 communicates over the HART® 7 protocol and comes with the proven EXPERTplus valve diagnostics with optimized features. To facilitate operation, the positioners are fitted with a plain-text display that indicates the condensed state according to NAMUR, measured values, start-up settings as well as messages in English or German. TROVIS 3730-3 is additionally ready for interconnection with SAM CHEMICALS, the cloud-based business application for the process industry.

The Series 3730 Positioners, which have been on the market for 15 years, includes several positioner models with varying electronic components and the associated different features, such as ease of operation, range of functions, communication and diagnostics. While the Type 3730-0 gets by without a microprocessor and is reduced to the essential functions, the 3730-1 and higher positioner models use digital signal processing for automatic start-up. Optional equipment, such as limit contacts, binary inputs and outputs, external position sensor and solenoid valve, ensures that the positioner configurations can be adapted to specific customer requirements.
