Introduction to Butterfly Valve
A butterfly valve is a type of quarter - turn valve that uses a disk - shaped closure element to regulate or isolate the flow of fluid in a pipeline. The disk rotates around a shaft perpendicular to the flow direction. When the disk is parallel to the flow, the valve is fully open, allowing maximum flow. As the disk rotates, the flow area gradually decreases until it is perpendicular to the flow, completely shutting off the passage. Butterfly valves are widely used in various industries such as water treatment, oil and gas, power generation, chemical processing, and HVAC systems due to their compact design, low cost, quick operation, and relatively low pressure drop.
