Fisher 1061

Fisher 1061 ActuatorFisher 1061 pneumatic piston rotary actuators are used to operate splined-shaft rotary control valves such as Vee-Ball valves, eccentric disc valves, and butterfly valves. The actuator/valve body linkage of this actuator can be positioned for either push-down-to-open or push-down-to-close action.

Additionally, the 1061 actuator can be used with a two-position control signal for on-off service or with a valve positioner for throttling service. An optional handwheel actuator is also available to allow for auxiliary or emergency manual valve operation when the 1061 piston actuator is not in use.

Features

  • Application flexibility
  • Minimal dead band - single point linkage with splined and clamped lever minimizes lost motion and improves control accuracy
  • Compact construction with overall size reduced by as much as 30% compared to similar actuators
  • Long service life - rugged construction provides stabilitly, corrosion resistance, and protection from deformation should the actuator be over-pressured
  • Accessibility - valve packing and adjustment remains accessible without removing any parts
  • Monitoring ease - highly visible travel indicator allows easy determination of valve position
