Features

  • The compact design reduces valve/actuator envelope dimensions leading to greater mounting versatility for both skids and process plants.
  • Allows linkage-less feedback, via a contact-less magnetic array.
  • The clamping of the lever onto a splined valve shaft, coupled with the single pivot linkage, reduces lost motion between the actuator and the valve.
  • The nested spring design requires no bench set.
  • The actuator can be mounted directly onto non-spline shafts, which allows mounting on a wider range of valves.
  • Ability to adjust or change the travel range by 30 degrees in either direction without removing the actuator or the addition of extra parts.
  • All parts in the fail-safe mechanism (made of steel, cast iron, and ductile iron) ensure the actuator will maintain safety integrity in the event of a fire.
  • The actuator/valve assembly action can be converted from push-down-to-open to push-down-to-close, or vice-versa, without additional parts.
