Features of Fisher™ 2052 Spring-and-Diaphragm Rotary Actuator

• 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.
