The compact diaphragm check valves use a flexible elastomer disc to deliver reliable, low-pressure sealing. In addition, the disc responds to extremely minimal pressure, allowing the valve to open easily. The self-centering design of the disc ensures that it seals in the exact same position every time, improving reliability and extending service life. As inlet flow passes through the valve, it continuously flushes the disc, keeping the sealing surface clean and free of particles, minimizing the risk of leakage.

Note: Check valves depend on gravity for sealing in low flow applications. Install check valves so gravity allows the disc to sit against the valve seat when flow is not present.
