Flap Valve

Flap Valves, sometimes referred to as Flap Gates, are put on the end of a flanged pipe to allow the flow of water out of the pipe, but prevent anything from flowing back in, such as sticks, leaves or other debris Under direct pressure the valve will open, and it will close when the pressure from outfall fluid is relieved.
