Eaton Propulsion check and relief valves

We provide a wide range of propulsion check and relief valves to the space industry. These valves ensure a one-way flow of hydrogen, oxygen and helium in rocket bi-propellant main propulsion systems and are designed to achieve and maintain high-flow rates even with low pressure drops.

EatonÕs check and relief valves reliably perform in the extreme environmental conditions found in space including high-mean operating pressures, high fluid flows and wide operational temperature ranges, including the cryogenic temperature range from _150 ¡C (_238 ¡F) to (_273 ¡C or _460 ¡F). In addition, our valves are high-shock and vibration tolerant, and the dual check valve features redundant flow capability.
