Pressure Relief Valves

Pressure relief valves from Technetics Group are designed to protect your pressure vessels, systems and components. Our engineers will tailor overpressure solutions to the specifications you require.

As with each of our solutions, the pressure relief valve solutions that we develop are custom-engineered for your critical applications. We have produced relief and check valves for since the time of the Apollo and Gemini  programs and more recently for the International Space Station and the Orion Spacecraft. Our pressure relief valves are suited for extreme conditions such as high vacuum, high pressure, cryogenic and high temperatures. Technetics Group provides full analytical, design and test support.

When used in conjunction with one of our SAFE-SHEAR™ Burst Discs, these valves prevent the loss of all media allowing pressure-dependent mechanisms to continue to function. We install our  SAFE-SHEAR™ Burst Discs and Pressure Relef Valves in the same housing thereby providing space and weight savings of 50 to 80% over other redundant systems.
