Function

41B8558X012 is valve trim spare component manufactured by Fisher. It fixes and positions internal trim parts, maintains coaxiality of plug and cage during valve movement. It reduces mechanical friction and vibration during fluid throttling. It ensures valve flow characteristic and seat tightness. It is essential spare part for control valve trim overhaul.

Installation

Follow lockout/tagout safety procedure before installation. Isolate pipeline and release process pressure. Disassemble valve bonnet, replace old 41B8558X012 component. Check assembly coaxiality and sliding clearance. Reassemble valve and perform hydrostatic test and seat leakage inspection.

Interface

Valve body internal mounting structure, fixed locating pins, no LED indicators on 41B8558X012.

Diagnostic

Valve internal leakage: Trim misalignment caused by worn component. Abnormal vibration noise: Trim assembly loose or component deformation. Valve sticking: Mechanical friction increase from worn spare part.
