Fisher 41B2047X012 Valve Cage

Technical Specifications

Model：41B2047X012 Brand：Fisher Product Type: Control valve internal valve cage

Module Feature

Fisher 41B2047X012 is precision multi-hole throttling cage for Fisher globe control valve. It forms core part of valve trim assembly. It adopts high strength alloy material with strong anti-cavitation and anti-erosion capability. The special hole design determines valve flow characteristic and reduces fluid noise. Widely applied in oil,gas,chemical and power plant high pressure control valves.

Working principle: Multi-hole fluid throttling and noise reduction Onboard components: Alloy cage body, locating sleeve, positioning pins

LED indicators

Not equipped

Hardware self-diagnosis

Visual inspection, dimensional measurement, internal surface wear inspection, leakage test

Programming software

No dedicated software required

Mechanical & Structure

Mounting: Installed inside globe control valve body Protection class:IP66

Environmental

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

System compatibility

Compatible with matched Fisher globe control valve and pneumatic diaphragm actuator for industrial process control system.

Function

41B2047X012 is core valve cage manufactured by Fisher. It works together with valve plug to realize staged pressure drop, suppress cavitation and fluid noise. Multi-stage orifice structure reduces fluid velocity and protects valve sealing surface from erosion. It directly decides valve flow capacity and flow curve. It is key spare part for high pressure differential control valve overhaul.

Installation

Follow lockout/tagout safety procedure before installation. Isolate pipeline and release process pressure. Disassemble valve bonnet, replace old cage assembly. Check cage alignment and plug clearance. Reassemble valve and perform hydrostatic test and seat leakage inspection.

Interface

Valve body internal positioning, fixed locating structure, no LED indicators on 41B2047X012.

Diagnostic

Valve noise and vibration: Cavitation damage or cage hole erosion. Reduced flow capacity: Cage hole scaling and blockage. Internal leakage: Cage deformation or misalignment.
