Houston Valve Repair & Modification Services

WH Labs provides industrial valve repair, modification, testing, and engineering services from our Houston facility. We serve customers throughout Houston and surrounding areas, such as Pasadena, Deer Park, Baytown, La Porte, and Channelview, supporting industrial facilities with valve inspection, repair, refurbishment, modification, machining, and testing services to restore performance and reliability.

Whether a valve is leaking, worn, corroded, operating poorly, or experiencing other performance issues, we evaluate its condition and determine the appropriate repair or modification approach.

Industrial Valve Repair Services

Proper valve repair starts with understanding the valve’s condition and the cause of the problem. WH Labs provides inspection and repair services designed to identify damaged or worn components and restore valves to their required operating condition.

Our capabilities include:

• Valve inspection and diagnostics
• Non-destructive testing (NDT)
• Component repair and replacement
• Valve seat re-seating and lapping
• Valve cleaning and refurbishment
• Valve reassembly
• Hydrostatic and pneumatic pressure testing
• Custom valve modifications

Where applicable, component replacements can be performed using genuine OEM parts to help maintain compatibility and performance.

Valve Modification & Engineering Services

Standard valves do not always meet the requirements of a specific industrial application. WH Labs can modify existing valves to address application-specific performance, material, flow-control, and functional requirements.

Our modification capabilities include valve trim and assembly modifications, actuator or positioner integration, precision machining, and other custom alterations based on the valve and its intended application.

Our in-house engineering capabilities and CNC machining centers allow us to perform precise modifications and component work for specialized valve requirements.

Types of Valves We Repair

WH Labs works with a range of industrial valve types, including:

Ball Valves: Common repair issues include seat and seal wear, leakage, and contamination-related damage.

Gate Valves: Repair requirements may involve stem, bonnet, sealing, and operating issues.

Butterfly Valves: Disc and seal damage, corrosion, erosion, and related wear may affect performance.

Check Valves: Damaged, warped, or improperly reseating discs can allow unwanted reverse flow.

Globe Valves: Stem and plug/disc wear and erosion can affect throttling and sealing performance.

Our Valve Repair Process

Our repair process is based on evaluating the individual valve and its condition.

1. Assessment & Inspection

We evaluate the valve to identify the reported problem and determine the scope of repair required.

2. Disassembly & Cleaning

The valve is carefully disassembled and cleaned so its components can be properly evaluated.

3. Detailed Inspection

Components are inspected for wear, damage, corrosion, cracks, and other conditions that could affect performance. Applicable NDT methods may be used when required.

4. Repair or Replacement

Damaged components are repaired, machined, or replaced as appropriate for the valve and application. Valve seats may also be re-seated or lapped when required.

5. Reassembly

The valve is reassembled with attention to component alignment, sealing, gaskets, and applicable specifications.

6. Testing

Repaired valves undergo applicable testing, including hydrostatic or pneumatic pressure testing, to verify pressure integrity and performance.

Common Reasons Industrial Valves Need Repair

Industrial valves can require repair because of:

• Leakage
• Wear and tear
• Corrosion
• Damaged sealing surfaces
• Sticking or operating difficulties
• Component damage
• Pressure-related problems

Early inspection and appropriate repair can help address these problems before they result in greater equipment or operational issues.
