SAMSON focuses on smart control valves for IoT environments including positioners with communication and diagnostic features. The spotlight is on the TROVIS 3793 Positioner for large actuators: modular design and wear-free, contactless travel sensing reliable even in critical conditions. It is presented on a cage valve with tandem actuator.
The cage-guided Type 3591 Valve (up to NPS 32, Class 900) with flanged seat ensures optimal absorption of forces and easy maintenance. A balanced piston acts as closure member. An adjustable PTFE or graphite packing seals the piston rod. For protection, the valve has an anti-rotation fixture.
The Type 3271 Pneumatic Actuator (two 2800 cm² rolling diaphragms, 250 mm rated travel) provides various bench ranges by varying the spring number and compression. Its features: powerful thrust at high stroking speed and low friction.
