Fisher V138763X012 Disc Pin Assembly

Technical Specifications

Model：V138763X012 Brand：Fisher Product Type: 04-300 rotary control valve disc pin assembly

Module Feature

Fisher V138763X012 is precision machined alloy disc pin assembly for Fisher 04-300 rotary control valve. It serves as mechanical transmission component to transfer actuator rotary motion to valve disc, realizing valve opening and closing. High strength alloy material offers good wear resistance and torque transmission capacity under cyclic rotation service. This part is discontinued, used for maintenance of existing 04-300 rotary valves in oil,gas and chemical plants.

Working principle: Transmit rotary torque from actuator to valve disc to modulate fluid flow Onboard components: Alloy disc gear, locating pins, flange base, fastening bolts

LED indicators

Not equipped

Hardware self-diagnosis

Visual inspection, gear tooth wear & crack inspection, torque transmission test, valve rotation smoothness test after assembly

Programming software

No dedicated software required

Mechanical & Structure

Mounting: Installed inside 04-300 rotary valve body between actuator shaft and valve disc Protection class:IP66

Environmental

Operating temperature:-40℃ ~ +425℃ Ambient humidity:5~95% non-condensing Certification:CE Status:Fisher discontinued rotary valve mechanical spare assembly

System compatibility

Exclusively for Fisher 04-300 series rotary control valve, matched with rotary pneumatic actuator and FIELDVUE digital valve controller.

Function

V138763X012 is core torque transmission assembly manufactured by Fisher. It transfers rotary movement from actuator to valve disc, changing flow area to regulate medium flow. Gear tooth abrasion, pin fracture will cause torque loss, valve rotation stuck or position deviation. It is essential mechanical spare for 04-300 rotary valve overhaul.

Installation

Follow lockout/tagout safety procedure before installation. Isolate pipeline and release residual process pressure. Disassemble rotary valve upper housing, replace old V138763X012 disc pin assembly. Align gear teeth and locating pins properly. Reassemble valve, perform air tightness test and full stroke rotation calibration.

Interface

Flange bolt mounting, gear meshing transmission between actuator shaft and valve disc, no LED indicators on V138763X012.

Diagnostic

Valve cannot rotate: Pin breakage or gear tooth severe wear. Position feedback deviation: Gear tooth abrasion and backlash increase. Abnormal mechanical noise: Gear tooth damage or insufficient lubrication.
