Our ability to diagnose operational issues with your valves allows us to make upgrade and modification recommendations that will improve performance. Typical modifications include:

Metallurgy upgrades to address changes in your process conditions
Bellows installation in pressure relief & safety valves to negate back pressure build up in outlet piping
Stem extensions to improve operation ergonomics of isolation valves
Gearbox sizing to improve opening or closing time of isolation valves

Our facility has steam, air, and water test stands that have been qualified by the National Board of Boiler Inspectors (NBBI) for pressure relief & safety valve testing. We test the valve set points per the National Board Inspection Code VR program. Valve seat tightness is tested per API Standard 527. Once a valve leaves our facility, you are ensured that it will perform as new.

Our O₂ clean room makes us unique among regional valve repair centers. Many industrial gas customers use our facility to clean new and repaired valves and regulators that require degreasing due to contact with oxygen, fluorine, or other processes.

Our cleaning facility is segregated from our main shop and employs air filtration systems to ensure that no unwanted particulate will come in contact with your valve. We use a dedicated oil-free air compressor to supply our stainless steel test stand. Black lights are employed to ensure hydrocarbons have been removed and the cleaning is complete.

We have the ability to clean all types of valves and instrumentation to your stringent standards and specifications.
