BUTTERFLY VALVE

DESCRIPTIONS :

Butterfly valve is a flow regulating disc valve, rotary valves in which a disc – shaped closure member is rotated through 90º, or about to open or close the flow passage. The main function of these valves is to control the flow of liquids through a section of pipe. Butterfly valves are mainly used in waste treatment systems. 

Butterfly Valve movement of the disc will depend on whether the valve is open or closed either partially or completely. If the valve is opened partially, it means that the disc will not be rotated a full one quarter turn, thus it cannot provide unrestricted passage. This means that, smaller amounts of fluid or air will pass through. However, if the valve is opened completely, the disc will be rotated 90 degrees then larger amounts of air or fluid will pass through.
