Samson 3271 Pneumatic Diaphragm Actuator

Samson 3271 Pneumatic Diaphragm Actuator is designed for all industrial applications. This actuator is a linear motion device ideal for valve sizes ranging from the micro-flow valves to large 20"+ globe control valves. The thrust force of the actuator depends on the actuator area, pneumatic supply pressure, spring stiffness, distance traveled, initial compression of the spring, the number of springs internal to the actuator, etc. The Type 3271 is a field-reversible, multi-spring diaphragm actuator that allows changing of fail-safe action. The Samson 3271 actuator offers uniform application of actuator forces to control valve as well as reduce height and weight of valve. The Actuator, together with positioner, can be rotated a complete 360 to allow for ease of local operation regardless of valve orientation.
