Fisher™ 3024C Pneumatic Diaphragm Actuator
Fisher 3024C Actuator
The Fisher 3024C actuator is a compact, spring-opposed pneumatic diaphragm actuator.
It incorporates a cast yoke mounting and is suitable for general purpose actuation of globe valves. This actuator will position the valve plug in response to varying controller or valve positioner pneumatic output signals applied to the actuator diaphragm. The 3024C actuator can be assembled as either direct-acting or reverse-acting and provides dependable and on/off or throttling operation of automatic control valves.

  • With eight different configurations available, there is an actuator size to meet your needs.
  • The simple design allows the change of action from direct to reverse-acting without the requirement for extra parts.
  • The molded diaphragm and high-strength casings allow for a maximum casing pressure of 6 bar, enabling a high stem thrust for a given size diaphragm.
  • Split block stem connection provides a solid transfer of motion while allowing easy mounting and no linkages that create lost motion or inaccurate valve positioning.
  • The cast steel yoke and heavy duty steel casings provide stability, protection against corrosion, longevity, and resistance against misuse.
  • Through careful selection of construction materials, this actuator can be used for a wide range of ambient temperature conditions.
  • The compact size minimizes weight and space needed.
