FLAP VALVES

Flap valves are designed to operate under very low heads of water, in gravity flow applications, at ambient conditions between -65° and +85° C. The valve prevents backwater via a spring-loaded or weighted flap placed across the opening of a pipe.

The Flap Valve incorporates a lip seal, to provide the seal between the flap and frame, and also a self-adhesive neoprene seal to install between the frame and wall, which is fitted to prevent leakage.

SHREE KRISHNA offers wall-mounted flap valves up to and including 1500mm in size and spigot-mounted flap valves up to and including 1000mm. Flange-mounted, tidal flap valves and bespoke flap valves are available on request.
