Our range of flap valves and flap gates includes wall mounted flap valves, tidal flap valves, flange mounted flap valves as well as push fit and pipe mounted flap valves. As standard our HDPE flap valves have a 50 year design life.
Flap valves and flap gates are a type of non-return valve (NRV) used to prevent flooding and to stop water back-flowing up pipework connecting into ponds, ditches, swales, rivers and marine or tidal environments.
We are able to design and manufacture bespoke flap valves for square, rectangular or elliptical openings or provide additionally reinforced ballast flap valves for when the valve is subject to wave action.
