Introduction to Butterfly Valves
A butterfly valve is a type of quarter - turn valve that uses a disk - shaped closure element to control the flow of fluid through a pipe. The disk rotates around a central axis perpendicular to the flow direction. When the disk is parallel to the flow, the valve is fully open, allowing maximum flow. When it is perpendicular to the flow, the valve is fully closed, blocking the flow. Butterfly valves are widely used in various industries such as water treatment, chemical processing, power generation, and HVAC systems due to their simple structure, low cost, and quick operation.
