RZN
The duo-eccentrically mounted disc is hydrodynamically 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.
