IPS Flap Valve Irrigation Pumping Station

Flap Valves are valves that allow movement only to a single way and are installed at the open end of a culver or pipeline. Their function is to allow downstream water to exit the pipe through a one-way flap door and prevent the rising water levels outside of the pipe from entering the pipe and flowing back up the system and flooding the protected area. Flap Valves are corrosion resistant and lightweight and they act like Check Valves and Non-Return Valves for the prevention of reverse flows. Traditional Flap Valves are manufactured from Cast Iron which has access to these, our standard range of Flap Valve is manufactured from HDPE which is a high strength, thick material which provides a whole bunch of benefits. They are available in several forms for most of the installation methods. The Flap Valves can be spigot and wall-mounted or also be obtained as flange mounted.

These Valves incorporate several sealings for ensuring leak prevention into the pipe system. AN integrated lip seal that is made up of EPDM can create a watertight seal between the body and the flap of the valve. All the flap valves are offered with a strip of self-adhesive neoprene for offering a seal between the wall and the valve or pipe.
