Fully lined fluorine butterfly valves are widely used in anti-corrosion pipeline systems. Mainly used to achieve the opening, closing, and adjustment of valves. Fully lined PTFE (F4), PTFE (F3), and PTFE (F46) fluoroplastic lined valves have the advantages of corrosion resistance, no leakage, and long service life. Suitable for concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, aqua regia, various organic acids, strong acids, oxidizing media or high-temperature sulfuric acid, high-temperature concentrated acetic acid, acid-base alternation, various organic solvents and other strongly corrosive media.

Fully lined fluorine butterfly valve has excellent anti-corrosion performance and can be applied to any concentration of acid, alkali, salt, oxidant, reducing agent, organic solvent, etc. It has the advantages of corrosion resistance, no leakage, and long service life. Suitable for concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, aqua regia, various organic acids, strong acids, oxidizing media or high-temperature sulfuric acid, high-temperature concentrated acetic acid, acid-base alternation, various organic solvents and other strongly corrosive media.

Fully lined fluorine butterfly valve is a type of valve that uses a disc type opening and closing element to rotate back and forth about 90 degrees to open, close, and regulate fluid channels. The structure is simple, the volume is small, the weight is light, the material consumption is low, the installation size is small, the driving torque is small, the operation is simple and fast, and it also has good flow control function and closing sealing characteristics,

The fully lined fluorine butterfly valve is suitable for use in pipelines with various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid, and various organic acids, strong acids, and strong oxidants. It is also suitable for use in pipelines with various concentrations of strong alkaline organic solvents, as well as other corrosive gases and liquid media. It is to place polytetrafluoroethylene resin on the inner wall of steel or iron valve pressure parts or the outer surface of valve internals by molding embedding method.
