A butterfly valve is a versatile flow-control valve widely applied in low-pressure pipeline systems. Its opening and closing component is a disc-shaped butterfly plate that rotates around the valve stem to achieve opening, closing, or flow regulation.
It is suitable for handling various media such as water, air, gas, steam, oil, chemical fluids, and other corrosive or non-corrosive materials. In pipeline systems, butterfly valves mainly perform functions of cut-off, throttling, and flow adjustment. With features including simple structure, small volume, light weight, and quick operation, butterfly valves are extensively used in industries such as water supply and drainage, HVAC, petrochemical, and power engineering.
