Flap valve Socket

The non return valve can be installed both indoors and out. Installation that allows easy inspection, inside an accessible recess, in an inspection pit, or in sight installation on a pipeline with support brackets, is always recommended.
The flap valves allow the waste water to flow out from a pipe to either a ditch or a pond, preventing back flooding at the same time. The flap is opened by waste water’s thrust. Flap’s weight and 11° slant keep the device closed when not working.
note : Material: PVC-U complying to EN1401 - Flap seal, EPDM + CR closed cell expanded rubber - Hinge: stainless steel AISI 304 with self locking nut - Flap closure tilt 11° - Up Ø 200 supplied in carton box
