Function

1U222946172 is core trim support component manufactured by Fisher. It supports and positions internal valve trim assembly, maintains coaxiality between valve plug and cage during stroke movement. It reduces fluid vibration and mechanical friction during throttling, stabilizes flow characteristic and guarantees seat shutoff performance. 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 1U222946172 component. Verify trim coaxiality and sliding clearance. Reassemble valve assembly and perform hydrostatic test and seat leakage inspection.

Interface

Valve body internal locating groove, locating pin holes, no LED indicators on 1U222946172.

Diagnostic

Valve internal leakage: Trim misalignment caused by worn support component. Abnormal vibration and noise: Component deformation or loose trim assembly. Valve sticking: Increased mechanical friction of moving trim parts.
