RZN

Check valve RZN

Complete pump protection in sophisticated areas

The check valve RZN has an excellent record of reliability in critical applications where other valves have failed.

The duo-eccentrically mounted disc is hydrodynamically designed for low pressure loss and freedom from jamming at the seat. The special damping system of the check valve RZN ensures tight and progressive shut-off against reverse flow and offers long service life.
