The fluorine lined butterfly valve adopts a fluorine lined plastic coated butterfly plate with a spherical sealing surface, and the silicone rubber liner at the base of the valve seat is used to adjust the sealing performance of the valve. The valve is easy to operate, tight sealing performance, long service life; It can be used to cut off or adjust the flow quickly. Suitable for applications requiring reliable sealing and good regulating characteristics. The valve body adopts split type, the sealing of the valve shaft is controlled by the rotating base surface of fluorinated rubber between butterfly plate and valve seat, so as to achieve compact structure, beautiful appearance, reasonable process and reliable performance. Ensure that the valve shaft is not in contact with the fluid medium in the chamber, it is very convenient to replace the valve shaft, the valve can be completed without removing the pipe. The products are widely used in various types of industrial pipeline liquid and gas transportation (including steam), especially with severe corrosive media such as sulfuric acid, hydrofluoric acid, phosphorus, acid, chlorine, strong alkali, aqua regia and other strong corrosive media.
