Electric fluorine-lined butterfly valve (also known as corrosion-resistant electric butterfly valve / electric fluorine-lined butterfly valve) is composed of electric actuator and fluorine-lined butterfly valve body, butterfly valve is a butterfly valve with the stem rotating together as the opening and closing parts, to achieve valve opening, closing and adjustment. Electric-operated fluorine-lined butterfly valve is a kind of polymer material with thick lining technology on over-flow parts, valve body, butterfly plate and valve stem. It has excellent anticorrosion performance. Corrosion-resistant electric butterfly valve can be used in any concentration of acid, alkali, salt, oxidant, reductant, organic solvent and other media. It is chemical, petroleum, pharmaceutical, food, iron and steel. Ideal products for intercepting and regulating equipment on gas, liquid, semi-fluid pipes and containers in metallurgical, papermaking, and hydroelectric systems can replace gate valves, globe valves, and other types of cut-off and regulating valves.
The electric fluorine butterfly valve has the advantages of corrosion resistance, no leakage and long service life. Electric lined tetrafluoro 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 olefinic acid, high temperature concentrated acetic acid, acid-base alternation and a variety of organic solvents and other strong corrosive media.
