Fisher 2V371946192 Control Valve Seat Ring Assembly

Technical Specifications

Model：2V371946192 Brand：Fisher Product Type: Hardened alloy seat ring assembly for globe control valve

Module Feature

Fisher 2V371946192 is precision hardened alloy seat ring for Fisher globe control valve trim. It forms sealing surface matching with valve plug to realize fluid shutoff. Hardened material provides excellent anti-erosion,anti-cavitation and wear resistance under high differential pressure service. Widely used in oil,gas,chemical and power plant globe control valves.

Working principle: Cooperate with valve plug to form sealing surface for fluid shutoff Onboard components: Hardened alloy seat ring, locating sealing gasket

LED indicators

Hardware self-diagnosis

Visual inspection, sealing surface scratch & cavitation inspection, dimensional measurement, seat leakage test after assembly

Programming software

No dedicated software required

Mechanical & Structure

Mounting: Installed inside valve body, positioned below cage assembly Protection class:IP66

Environmental

Operating temperature:-40℃ ~ +425℃ Ambient humidity:5~95% non-condensing Certification:CE Status:Fisher valve trim spare part

System compatibility

Compatible with matched Fisher cage, valve plug and valve stem, works with pneumatic diaphragm actuator and FIELDVUE positioner.

Function

2V371946192 is core sealing component manufactured by Fisher. It matches valve plug to realize tight shutoff. When valve closes, plug contacts seat ring to cut off fluid flow. Scratches, cavitation erosion or deformation on seat surface will cause valve internal leakage. 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, remove old seat ring. Clean valve body cavity, install new 2V371946192 seat ring and gasket. Reassemble valve trim, perform hydrostatic test and seat leakage inspection.

Interface

Press fit / threaded locating inside valve body cavity, sealing face mates with valve plug, no LED indicators on 2V371946192.

Diagnostic

Valve internal leakage: Seat ring sealing surface scratch, cavitation or deformation. Capacity deviation: Seat ring orifice scaling and blockage. Trim assembly stuck: Seat ring installation misalignment.
