Introduction to Butterfly Valve
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 pipe’s axis. When the disk is parallel to the flow direction, the valve is fully open, allowing maximum flow. As the disk is rotated, the flow is gradually restricted until it is completely shut off when the disk is perpendicular to 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.
