Coaxial Solenoid Valve (CSV)

Valiant Space’s coaxial solenoid valves are normally closed, 1-way shut-off valves that utilises a direct acting, spring-loaded poppet to provide reliable actuation and sealing throughout all stages of spaceflight. The coaxial design allows for low pressure drops whilst remaining compact and low mass. The valve comes standard with inlet and outlet weldable tubes, with other process connections available upon request.
