COAXIAL SOLENOID VALVE

IN ORBIT SINCE 3RD JAN 2023

Valiant Space’s coaxial solenoid valves are normally closed shut-off valves that utilise a direct acting, spring-loaded poppet to provide reliable actuation and sealing throughout all stages of spaceflight. The co-axial 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
