Flap Valve
Automatically actuated by the water pressure, our flap valves prevent backflow from basins or sewers. Ideal for rainwater drains and retention basins. Depending on the application, the flap valves can be equipped with an additional counterweight. A lip seal ensures reliable shut-off. The stainless steel constructions are available in round and square shapes.
