Product Description

Fisher 685 series piston actuators provide medium to high thrust output for a variety of medium to very large Fisher sliding-stem valves, including the easy-e™, HP, EH, FB, and 461 valves. The double-acting design of the actuator results in stiff, precise positioning. Spring-return constructions are also available and offer a fail open or closed mode of operation when paired with a valve.
