Fisher 585C

Fisher 585C ActuatorThe 585C linear piston actuator is a powerful, double-acting actuator that provides accurate throttling or on-off operation for sliding-stem control valves.

THe 585C piston actuator family is available in sizes 25 to 130 to cover a wide range of thrust and travel length requirements. It can be used with switching valves for on-off control, or with the DVC6200 digital valve controller or 3600 positioner for throttling applications.

The 585C has a wide range of supply pressure capabilities, up to 150 psig. As the 585C is double-acting, the positioner supplies air to both sides of the piston, resulting in stiff, precise movement and control.


  • High trust capability - with standard air supply, the size 130 fisher 585C can produce up to 111,000 Newtons (25,000 lbs) of force
  • Rugged construction - the 585C standard yoke material is ductile iron, resulting in robust construction and increased thrust capability
  • Broad travel capability - 585C piston actuators provide standard travel lenghts of up to 203 mm (8 inches)
  • High-performance instrumentation - 585C actuators are available with a variety of positioners and accessories, including the FIELDVUE DVC6200 digital valve controller. The 377 trip valve and tank system are also available for fail-safe action.
