Valve leaks are unique and almost always consist of a custom design.
Valve leaks are quite common and can arise in many locations on or around the valve. The most common leakage paths are:
- Valve Bonnet Leakage
- Failed welds
- Corrosion through the pipe threads
- Thinning of the valve body
Common sealing techniques and designs
The leak sealing techniques for valves are typically the same as those for other piping components. See our page Piping Leaks page for more information.
Active Stem Valve Enclosures
In some applications the valve must remain operational while sealing off the existing leak. EngRx designs multi-part enclosures called Auxillary Stem designs (also known as Active Stem) which seal the leakage, and then integrate with the existing valve allowing the valve to be operated.
