Butterfly Valve: An In-Depth Mechanism You Need To Know
The butterfly valve is a type of one fourth-turn rotary motion valve which is used as a throttling valve to control and regulate the flow through a system. Butterfly valve has its own set of advantages which include good control capabilities, quarter-turn, and openness for diminished plugging systems. Further, the capability of butterfly valves to work in areas with limited space and deliver a high coefficient of flow makes them an important part of industries today. However, since it is difficult to clean their internal parts, they are not recommended to be used in industries like medical and food processing applications where sterility is an important factor. CONTROL METHODS OF BUTTERFLY VALVES Butterfly valves function by controlling the flow of the liquid that passes through them depending on the method of control. A butterfly valve consists of a metal circular disk, also called vane. This disc pivots at a right angle to the axis of the direction of flow in the pipe. When the
