Check Valves | NR-010 Wafer Style Check Valve

NR-010 Check Valve

Description
The NR-010 Check Valve prevents the return flow of water to its source and provides quiet closure and total sealing of the sealing face. It has a quick, spring-assisted closure that minimizes the possibility of water hammer and is designed for free flow of water without interference and with minimal head loss.
The check valve is compatible for installation on pipelines with horizontal pumps or boosters. The check 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.

Applications
- After pumps/boosters
- Filtration systems
- Swimming pools (additional modifications are required for this application)
- Fertilizer system
