The NR-034 Swing-Type Non-Return Valve allows for one directional flow and prevents the return flow of the liquid to its source.

This check valve is designed for installation on horizontal pumps, boosters and filtration systems, preventing return flow and providing for quiet closure and total sealing of the sealing face.
The length of the NR-034 check valve is designed to allow installation between two flanges of short spacing, allowing for installation of the check valve in small and narrow systems.
