Flap valve Flange
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.
