Product Description
Check Valves are automatic shut-off valves that are commonly used for preventing back flow or drainage in a piping system.

Wafer Type Single Disc Swing Check Valves are designed for installation in flanged piping systems, between two flanges. Valves may be installed in vertical or horizontal piping.
