NR-010 | Wafer Style Check Valve
The NR-010 check valve is compatible for installation in horizontal pumps or boosters for gardening and agriculture. The check valve prevents the return flow of water to its source and provides quiet closing and total sealing of the sealing face. The NR-10 check valve is designed for free flow of water without interference and with minimal head loss. The valve is made from composite materials to withstand highly abrasive conditions and to ensure long-term service in corrosive liquid environments such as seawater, brine and chlorine water.
