The fluorine lined butterfly valve adopts a PTFE lined butterfly plate with a spherical sealing surface, and is equipped with a silicone rubber gasket at the base of the valve seat to adjust the sealing performance of the valve; The valve is easy to operate, has tight sealing performance, and has a long service life; Can be used to quickly cut off or adjust flow. Suitable for occasions that require reliable sealing and good adjustment characteristics.

Suitable for the transportation of liquids and gases (including vapors) in various types of industrial pipelines, especially in applications with highly corrosive media such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine gas, strong alkali, aqua regia, etc.

Product Structure Features:

The valve body of the fluorine lined butterfly valve adopts a split type, and the sealing at both ends of the valve shaft is controlled by adding fluorine rubber to the rotating base surface between the butterfly plate and the valve seat; Thus achieving a compact product structure, beautiful appearance, reasonable craftsmanship, and reliable performance. Ensure that the valve shaft does not come into contact with the fluid medium inside the chamber, making it very convenient to replace the valve shaft. The valve can be completed without removing the pipeline.
