Introduction to Butterfly Valve
A butterfly valve is a type of quarter - turn valve that uses a disk - shaped closure element (the "butterfly") to control the flow of a fluid through a pipe. It rotates around a central axis perpendicular to the flow direction. When the valve is fully open, the disk is parallel to the flow, allowing maximum flow rate. As the valve is closed, the disk rotates, gradually restricting the flow until it is completely shut off when the disk is perpendicular to the flow. Butterfly valves are known for their simplicity, compact design, and relatively low cost compared to other types of valves. They are widely used in various industries such as water treatment, chemical processing, power generation, and HVAC systems.
