Check valve

Non-return valve: 6 models to choose from!

35,00 € tax incl.

Check valve specially designed to limit pressure losses.

This valve does not have a ball or a spring, but a flexible valve which causes much less pressure loss.

This accessory can be installed vertically or horizontally (in the latter case, be careful to respect the position indicated on the valve body).

Available in 32 (*), 50, 63 and 90 mm, always without spring to limit the pressure losses.

(*) Valve whose diameter measures exactly 33 mm but delivered with 32 mm accessories

All these valves can be glued without any difficulty with Griffon WDF-05 glue.

Two brands are available here: Valterra or NDS Inc. (choose from the drop-down menu)

The internal diameters are:

32 mm / 1 "- 27 mm valve NDS Inc

Valve 50 mm / 1½ - 42 mm NDS Inc OR Valterra

63 mm / 2 "- 54 mm valve NDS Inc OR Valterra
