Mechanical & Structure

Mounting: Installed inside pneumatic diaphragm actuator Protection class:IP66

Environmental

Operating temperature:-40℃ ~ +120℃ Ambient humidity:5~95% non-condensing Certification:CE Status:Fisher actuator spare part

System compatibility

Compatible with Fisher 657,658 series pneumatic diaphragm actuators and globe control valves for industrial process control system.

Function

52601428 is actuator spare component manufactured by Fisher. It transfers linear thrust generated by diaphragm to valve stem, maintains stable linear movement during valve modulation. It reduces lateral vibration and mechanical friction during stroke travel. It guarantees actuator output thrust and valve positioning repeatability. It is essential spare part for actuator overhaul.

Installation

Follow lockout/tagout safety procedure before installation. Cut off instrument air supply and release residual pressure. Disassemble actuator casing, replace old 52601428 component. Verify sliding clearance and alignment. Reassemble actuator and perform air tightness test and full stroke calibration.

Interface

Actuator internal mounting structure, fixed mounting holes, no LED indicators on 52601428.

Diagnostic

Unstable valve stroke: Worn spare part or loose fastener. Insufficient actuator thrust: Component deformation or fatigue. Valve sticking: Increased mechanical friction of moving parts.
