Check Valves

Aerospace check valves allow fluid flow in one direction and, if the system pressure or flow reverses, close quickly to prevent flow in the opposite direction. Aerospace check valves are normally self-contained, spring-loaded devices, requiring no external actuation signals or sources of power.

AVI can provide numerous styles of check valves to meet requirements for operating pressures, temperature, actuation or cracking pressure, closing pressure, flow requirements and leakage. Valves are available in several standard types of check valves, including poppet style; swing flapper (inline and bulkhead mount), and split butterfly styles.
