Flap Valve: Ensuring Unidirectional Flow for Water and Sewerage
A flap valve, also known as a non-return valve (NRV), serves a crucial role in enabling water or sewerage to flow in one direction only. These valves operate as water flows through a pipe or culvert, pushing open the swinging door. As the water level rises downstream, the swinging door closes, effectively preventing flooding and the reverse flow of water within the system.
