What is a Butterfly Valve
What is a Butterfly Valve?
A butterfly valve is a type of quarter-turn valve that is used to regulate the flow of fluid through a pipe. The valve contains a rotating disc that is positioned in the center of the pipe, which can be turned to open or close the valve. This simple yet effective mechanism offers numerous advantages in fluid control applications. Below, we’ll explore various aspects of butterfly valves that highlight their importance and functionality in different industries.
