Eaton’s cabin pressure relief and isolation valves are integral safety components of pneumatic pressurized airlock systems on space structures. Designed to accommodate manned and unmanned missions, our valves can support both manual and motor driven space systems. Our highly reliable cabin pressure relief and isolation valves help ensure the safety of crew, cargo, habitat and mission, and contribute to long term survivability and success of space exploration initiatives.
These compact, lightweight valves have completed multiple space missions on varied platforms and in diverse environments, as a result Eaton can provide pedigree with reduced lead times, qualification cycles and cost.
