Top 10 Butterfly Valve Factory in China

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 a fluid. It rotates around an axis perpendicular to the flow direction. When the valve is fully open, the disk is parallel to the flow, allowing for minimal flow resistance. When closed, the disk blocks the flow path completely. Butterfly valves are widely used in various industries such as water treatment, HVAC (Heating, Ventilation, and Air Conditioning), chemical processing, and power generation due to their compact design, low cost, and quick operation.
