In butterfly valves, the closing element is a rotating disc located on the vertical axis. When assembled, it rotates around its axis, forming a disc that opens or closes the full pipe section. Sealing is provided between the metal flap and the elastic or plastic sealing elements covering the inside of the body. The sealing element also acts as a gasket in the flange between the valve and the pipe.

Advantages of such valves; low pressure losses, easy opening and closing, good sealing, light weight and small footprint.

While Ayvaz BV-10 Butterfly Valves are being mounted, it should be checked whether the disc moves freely. Valve shaft can be in horizontal or vertical position. However, horizontal mounting should be preferred on DN300.
