Pneumatic Actuators

A pneumatic actuator provides high stem force output for demanding service conditions.  These actuators are usually air operated but some can be self operated by the process fluid.
  • Fisher® V150Diaphragm Actuators
    Fisher spring and diaphragm pneumatic actuators can be ''direct-acting'', meaning that air to the diaphragm casing pushes the actuator stem downward.
  • Fisher® 585CPiston Actuators
    Fisher linear piston actuators are powerful, double-acting actuators that provide accurate throttling or on-off operation for sliding-stem control valves.
  • Fisher® 1035/El-O-MaticRack-and-Pinion Actuators
    Fisher rack-and-pinion rotary actuators are available in both double-acting and spring-return configurations.
  • Fisher® 655Self-Operated Actuators
    Fisher self-operated valve actuators provide control for a variety of pressure regulation applications. These actuators can be self-operated or remote-operated.
