Description

The NR-050 Tilting Disc Check Valve allows one-directional flow and prevents the return of the liquid to its source. The valve disc is attached to the body by a shaft. Sealing is done by the disc closing up against the sealing seat located on the body. The diagonal sealing of the valve shortens the closure distance so the disc shuts quicker, lowering the potential for surge.
