Check valves are extremely simple devices yet they serve an important purpose in many pneumatic circuits. Generally used in systems where back flow is not permitted, check valves allow free flow in one direction and block flow in the opposite direction. They can also be used as a bypass valve, allowing media around components such as needle valves which restrict flow in both directions. To meet the needs of your application, Pneumadyne manufactures a variety of Check Valves with threaded... (read more)Browse Check Valves Datasheets for Pneumadyne, Inc. -
