The closing element in the butterfly valves is a rotating shaft that is placed on a vertical axis. The sealing is provided betvveen the metal flap and the elastic or plastic sealing elements covering the inside of the body. The sealing element also serves as a flange seal betvveen the valve and the pipe. Advantages of such valves are; low pressure loss, easy opening and closing, good sealing, light vveight and small footprint.

The Ayvaz KV-1 Wafer Type Butterfly Valves should be checked to see if they are moving freely during the installation. The valve stem may be horizontal or vertical. However, horizontal installation on DN300 should be preferred.
