HDPE Flap valve
Our flap valves were developed for flow control and backflow prevention. In the event of flooding, it is important that you can completely rely on your installed flap valves.

Our valves can be used in surface water, sewers, disposal systems  and other aggressive environments where reverse flow needs to be prevented. The water is controlled by automatically opening and closing the gate.
