Valve refurbishment refers to the process of restoring or renewing industrial valves to their optimal working condition. Valves are essential components used in various industries, including oil and gas, power generation, manufacturing, and water treatment. Over time, valves can become worn out, damaged, or inefficient due to factors such as wear and tear, corrosion, or operational issues. Refurbishing valves can help extend their lifespan, improve performance, and ensure reliable and safe operation
Servtech Technical Services LLC’s valve assemblies to our shops for inspection, testing, and full repairs. Our refurbishment capabilities allow us to quickly service what is needed to repair the valve and actuator in a timely manner along with keeping costs down. We are not at the mercy of OEMs to get parts and repair kits. We can also upgrade valve assemblies with new actuators and positioners to return the best possible product to our customers.
Servtech Technical Services LLC continues to deliver value to customers by applying the industry’s latest valve engineering techniques, some of which we’ve perfected beyond the OEM’s own capabilities. This has allowed us to continue to thrive and grow our business with unmatched performance and quality that is second to none.

Inspection & Testing
External Inspection - The Valve must be functionally inspected, open, and closed. The valve body must be checked visually for any cracks or cuts.
Pre-Testing - The Pre-test is done first for High-Pressure Closure, if found ok, then proceed to the rest of the applicable tests.
Dismantling & Internal Inspection - Soft kit is inspected, and size and specs are to be identified for replacement. Seat/ball situation to be recorded and determine the amount of work to be carried on the seat/ball. If not, then stop the Pre-testing at the High-pressure closure test, report, and proceed with the dismantling process.
All other mechanical valve parts are to be inspected and reported.
Overhauling And Repair - Seat Treatment - Seat treatment will be carried out as per
the inspection results (Lapping/ Machining) and Assembly as per manufacturer instructions.
