Fisher 1U239622012 Control Valve Plug Assembly

Technical Specifications

Model：1U239622012 Brand：Fisher Product Type: Hardened alloy valve plug assembly

Module Feature

Fisher 1U239622012 is precision hardened alloy valve plug assembly for Fisher globe control valve trim. It mates with seat ring to realize shut-off and flow modulation. Hardened sealing surface provides good anti-cavitation,anti-abrasion and anti-corrosion performance under high differential pressure. Widely used in oil,gas,chemical and power plant globe control valves.

Working principle: Linear movement to change flow area and realize valve opening/closing & shutoff sealing Onboard components: Alloy plug body, hardened sealing face, stem connection thread

LED indicators

Not equipped

Hardware self-diagnosis

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

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, seat ring, valve stem and pneumatic diaphragm actuator for industrial process control system.

Function

1U239622012 is core valve plug manufactured by Fisher. It cooperates with seat ring to achieve tight shut-off. It moves linearly with valve stem to change the flow passage area for fluid flow regulation. The sealing surface quality directly determines seat leakage performance. Cavitation erosion or scratches will cause internal leakage. It is key consumable 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 valve plug. Verify plug flatness and assembly fit with seat ring and cage. Reassemble valve trim and perform hydrostatic test and seat leakage inspection.

Interface

Thread connection with valve stem, sliding fit inside cage, sealing surface matches seat ring, no LED indicators on 1U239622012.

Diagnostic

Valve seat leakage: Plug sealing surface scratch, cavitation erosion or deformation. Flow capacity drop: Plug scaling or orifice blockage. Valve sticking: Plug surface galling and friction increase.
