List of featured suppliers of FLAP VALVES on Building Products Index
Flap valves are devices that allow fluids or gases to flow in one direction but prevent them from flowing back in the opposite direction. They consist of a plate or flap that is hinged along one edge and opens when the pressure of the fluid or gas exceeds a certain threshold. Flap valves are commonly used in drainage and sewage systems to prevent flooding or backflow of wastewater. They are also used in HVAC systems, pneumatic conveying systems, and other industrial applications.
