Samson Type 3271 Pneumatic Actuator, 1400-250 cm2

The Samson Type 3271 is a diaphragm pneumatic actuator with a rolling diaphragm and internal springs, built for mounting on SAMSON Series 240, 250, 280, 290, 590 and SMS control valves, with a 1400-250 cm2 actuator area and 250mm rated travel.

It delivers powerful thrust at high stroking speed with low friction, allows the bench range to be changed by varying the number or compression of internal springs without special tools, supports both FA (stem extends) and FE (stem retracts) fail-safe directions of action, and is rated for operating temperatures from -60 to +90 degrees C; it carries the EAC mark of conformity.
