Electric fluorine lined butterfly valve (also known as corrosion-resistant electric butterfly valve/electric PTFE lined butterfly valve) is composed of an electric actuator and a fluorine lined butterfly valve body. The butterfly valve uses a butterfly plate that rotates together with the valve stem as the opening and closing component to achieve the opening, closing, and adjustment of the valve. Electric fluorine lined butterfly valve is a high polymer material lined with thick lining technology on the flow components, valve body, butterfly plate, and valve stem. It has excellent corrosion resistance and can be applied to any concentration of acid, alkali, salt, oxidant, reducing agent, organic solvent, and other media. It is a gas and liquid in chemical, petroleum, pharmaceutical, food, steel smelting, papermaking, hydropower and other systems The ideal product for use as shut-off and regulating equipment on semi fluid pipelines and containers, and can replace gate valves, globe valves, and other types of shut-off and regulating valves. Electric fluorine lined butterfly valves have advantages such as corrosion resistance, no leakage, and long service life. The electric lined PTFE butterfly valve is suitable for concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, and various organic acids, strong acids, oxidizing media or high-temperature sulfuric acid, high-temperature concentrated acetic acid, acid-base alternation, as well as various organic solvents and other highly corrosive media.
