Flanged Clapet Valve
The Clapet backflow preventer valve is to be installed in white water discharge pipes and allows the normal outflow of water into water bodies by preventing backflow. This function is ensured by the opening of a "clapet" actuated by the thrust of water from the drain. The weight and 11° inclination of the clapet keep the opening closed.
