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 relief valve solutions that we develop are custom-engineered for your critical applications.
We have produced relief and check valves for programs since Apollo and Gemini, and more recently, the Orion program. Products are suited for extreme conditions such as hard vacuum, high pressure, cryogenic and high temperatures. Hydrodyne provides full analytical, design and test support.
