The closing element in the butterfly valve is the rotating shaft placed on the vertical axis. A seal is provided between the metal foil and the resilient or plastic sealing element that covers the interior of the body. The sealing element is also used as a flange seal between the valve and the pipe. The advantages of this type of valve are: low pressure loss, easy opening and closing, good sealing, light weight and small footprint.

Ayvaz KV-1 wafer type butterfly valves should be inspected to see if they are free to move during installation. The valve stem can be horizontal or vertical. However, the DN300 is preferred to install horizontally.
