In the butterfly valves, the closing element is a pivoting disc arranged on the vertical axis. It rotates around its axis in its assembled state to form a disc that opens or closes the full pipe section. The sealing is provided between the metal flap and the elastic or plastic sealing elements covering the inside of the body. The sealing element also serves as a seal on the flange between the valve and the pipe.
