High Pressure Multiway Valve
Pyroalliance designs and manufactures high pressure multiway valves for missile applications.
These complex hight pressure multiway valves, constituted of several ways, operate as a pyrotechnically triggered pneumatic distributor allowing the supply of pneumatic pressure to each of its ways.
The hight pressure multiway valves are designed to perform a tailored sequence of actions among which circuit opening, circuit closing, mechanical actuation…
Based on onboard available pneumatic pressure, a series of pyrotechnic orders successively triggers the required functions, thus combining several pyro-mechanisms in one single equipment.
More generally, Pyroalliance delivers complete pyrotechnic chains adapted to its customers’ needs. They are designed and manufactured under Pyroalliance’s design authority.
