Valve Reconditioning For industrial applications

JS Machine & Valve provides valve reconditioning services, valve repair services, and valve rebuild solutions for industrial applications where performance, sealing integrity, and reliability are critical. Our shop supports the restoration of valves used in refining, petrochemical, pipeline, and power generation environments.

Reconditioning services are used to return valves to service by addressing wear, internal damage, and performance degradation through controlled inspection, machining, and repair processes.

These Services Support:

High-pressure and high-temperature applications
Corrosive and erosive service environments
Severe service valve applications
Maintenance and turnaround programs

When Reconditioning is used

Component Wear & Damage

Used when parts show wear, erosion, or corrosion affecting performance.

Full Valve Rebuilds

Required when valves need complete internal restoration or overhaul.

Precision Machining Needed

Applied when tight tolerances and detailed inspection are necessary.

Turnarounds & Planned Maintenance

Common during scheduled outages and maintenance programs.

Repair vs. Replacement Decisions

Selected when restoring the valve is more practical than a full replacement.

The Process

Disassembly & Condition Assessment

Valves are fully disassembled and evaluated to determine wear patterns, damage, and overall condition.

Cleaning & Decontamination

Components are cleaned to remove scale, residue, and contaminants, preparing surfaces for repair.

Component Restoration

Worn or damaged components are rebuilt, repaired, or replaced to restore structural integrity and function.

Sealing Surface Reconditioning

Seats, bores, and critical sealing areas are machined or refinished to restore proper contact and sealing performance.

Reassembly & Operational Check

Valves are reassembled and adjusted to ensure proper alignment, movement, and functionality.
