Butterfly valves are a type of flow control valve commonly used in industrial applications to regulate the flow of fluids. They are named after the disc or plate inside the valve, which resembles the wings of a butterfly. Butterfly valves are known for their compact design, lightweight construction, and quick operation.
Butterfly valves consist of a circular disc or plate that is mounted on a spindle in the center of the pipe. The disc can be rotated to control the flow of fluid. When the disc is in a perpendicular position to the pipe, it blocks the flow completely, and when it is parallel, it allows maximum flow. Intermediate positions can be used to regulate the flow rate.
