The RZN has an excellent record of reliability in critical applications where other check valves have failed.
The duo-eccentrically mounted disc is hydrodynamical designed for low pressure loss and freedom from jamming at the seat. The special ADAMS damping system ensures tight and progressive shut-off against reverse flow and offers long service life.
The compact design allows installation in confined spaces. All internal screws on ADAMS non-return valves are mechanically locked.
