Check Valves

Check valve (one way valve) allows flow in one direction only. Internal seal checks reverse flow. Used in applications where back flow is not permitted, or must be redirected. Humphrey offers check valves from the miniature TAC family and specialty Check Valves (with override) from our Classic Diaphragm-Poppet Series. The Humphrey Quick Exhaust valves make excellent check valves by plugging exhaust port.
