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 diaphragm actuator and globe control valve for industrial process control system.

Function

49452 is actuator spare component manufactured by Fisher. It transfers diaphragm thrust to valve stem, ensures stable linear movement during valve stroke. It reduces mechanical clearance and vibration during modulation. 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 housing, replace old 49452 component. Check mechanical sliding clearance. Reassemble actuator and perform air tightness test and stroke calibration.

Interface

Actuator internal mounting structure, fixed mounting holes, no LED indicators on 49452.

Diagnostic

Valve stroke unstable: Worn spare component or loose fastener. Actuator output insufficient: Mechanical part deformation. Valve sticking: Increased friction caused by worn component.
