The electric lined fluorine butterfly valve (also known as the corrosion-resistant electric butterfly valve/electric PTFE-lined butterfly valve) consists of an electric actuator and a lined fluorine butterfly valve body. The butterfly valve uses a disc that rotates together with the valve stem as the closing element to achieve the opening, closing, and regulation of the valve. The electric lined fluorine butterfly valve employs lining technology on the flow-passing components, valve body, disc, and valve stem, with a thick lining of polymer material, offering excellent corrosion resistance. The corrosion-resistant electric butterfly valve is suitable for media such as acids, alkalis, salts, oxidants, reducing agents, and organic solvents of any concentration. It is an ideal product for use in pipelines and containers carrying gases, liquids, and semi-fluids in systems such as chemical, petroleum, pharmaceutical, food, steel smelting, papermaking, and hydropower, serving as a shut-off and regulating device. It can also replace gate valves, globe valves, and other types of shut-off and regulating valves.
