1¡¢ Overview of fluorine lined butterfly valves

The PTFE lined butterfly valve adopts a PTFE lined butterfly plate with a spherical sealing surface. The valve is easy to operate, has tight sealing performance, and an ultra long service life; It can be used for quickly cutting off or adjusting flow. Suitable for occasions that require reliable sealing and good adjustment characteristics. The valve body 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; Ensure that the valve shaft does not come into contact with the fluid medium in the cavity. Widely suitable for the transportation of liquids and gases (including vapors) in various types of industrial pipelines, and for use in severely corrosive media such as sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine gas, strong alkali, and other highly corrosive media.

2¡¢ Structural characteristics of fluorine lined butterfly valves

1. The design is novel, reasonable, and has a unique structure, with light weight and fast opening and closing.

2. Can be installed in any position, convenient for maintenance.

3. The sealing element can be replaced, and the sealing performance is reliable, achieving zero leakage in both directions.

4. Small operating torque, convenient operation, labor-saving and agile.

5. The sealing material has characteristics such as aging resistance, corrosion resistance, and long service life.
