Pneumatic fluorine-lined butterfly valve (also known as corrosion-resistant pneumatic butterfly valve) is composed of pneumatic piston actuator and tetrafluoro-sealed butterfly valve. Fluorine-lined pneumatic butterfly valve is a kind of high molecular material with thick lining technology on the over-flow parts, valve body, butterfly plate and valve stem. It has excellent corrosion resistance and can be applied to any concentration of acid, alkali, salt and oxidant, reducing agent, organic solvent, etc. Medium, pneumatic fluorine-lined butterfly valve is an ideal product for intercepting and regulating equipment in gas, liquid and semi-fluid pipelines and containers of chemical, petroleum, pharmaceutical, food, steel smelting, paper making, hydropower and other systems. Fully lined polytetrafluoroethylene (F4) and polyperfluoroethylene propylene (F46) fluoroplastic lined valves have the advantages of corrosion resistance, leak-free, long service life and so on. Corrosion-resistant pneumatic butterfly valve is suitable for concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, Aqua regia, 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.


Main features of pneumatic lining butterfly valve


1, small size, light weight, easy operation, easy installation and maintenance.


2, good sealing performance, reliable zero leakage and long service life.


3, the flow characteristics tend to be straight, and the regulation performance is the best.


4, simple structure, fast switching, 90 degree rotary opening and closing.


5, can replace gate valve, stop valve, plug valve, hose valve and diaphragm valve and other valves.


6. The pneumatic and electric devices can be configured to meet the needs of remote control and program control.


7, replacement of parts lining material can be applied to all kinds of media.
