One: About Pneumatic lining clip butterfly valve
Pneumatic lining clip butterfly valveWith a spherical sealing surface of PTFE lined butterfly plate, the valve is easy to operate, tight sealing performance, long service life, can be used for quick cutting or regulating flow. Pneumatic valves are suitable for applications requiring reliable sealing and good regulation characteristics. The valve body adopts split type, and the sealing at both ends of the valve shaft is controlled by the rotation base plate of the butterfly plate and the valve seat with fluorine rubber, and the valve shaft is not contacted with the fluid medium in the cavity. Transport is widely used in a variety of different types of industrial liquid and gas in the pipeline, there are serious corrosive media occasions, such as: sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, alkali, aqua regia and other strong corrosive media.
Two: pneumatic lining fluorine butterfly valve main features
1, The design is novel, reasonable, unique structure, light weight, fast opening and closing.
2, Small operating torque, easy operation, labor-saving and smart.
3, It can be installed in any position and convenient for maintenance.
4, Seals can be replaced, sealing performance is reliable, to achieve two-way sealing, zero leakage.
5, Sealing materials aging resistance, corrosion resistance, long service life and so on.
