Additional Info
Check Valves are mechanical devices that permit fluid to flow through them in one direction only. The valve often uses a ball and spring that opens under a specified pressure but closes as the pressure decreases to prevent backflow.
Key specifications include valve type, port connections, valve size, minimum and maximum pressure ratings, media, and materials of construction.
Check valves are used on gas lines, for air service, with pumpsanywhere that fluid needs to move in a single direction.
