NR 010 non-return valve (3” – 10”)

The existing NR 010 Series with 3” and 4” non-return valves has been extended to include a 6”, 8” and 10” version and is available in both 10 bar and 16 bar versions.
The successor to the 2 previous NR 010 and NR 020 types is the new nonreturn valve type: NR 010. This valve is a plastic, spring-loaded disc check valve that is installed between bushes and flanges. The NR 010 is available in both 10 bar (blue arrow) and 16 bar (red arrow) versions. This type promotes quiet closing and limits water hammer. This non-return valve has a completely free passage and hence low pressure loss, a particular benefit in intake lines. Thanks to its special soft seals and an extra smooth sealing surface, this non-return valve closes even with extremely low pressures. This valve is optionally available with a position switch or suction strainer.

The valve is available both loose and preassembled between PVC flanges and bushes.
