I. Pneumatic lining fluorine butterfly valve products
Pneumatic lining fluorine butterfly valve adopts PTFE lined lining plate with spherical sealing surface. Pneumatic lining fluorine butterfly valve is easy to operate, with tight sealing performance and long service life; it can be used for quick cutting or adjusting flow. Pneumatic-lined PTFE butterfly valves are suitable for applications where reliable sealing and good adjustment characteristics are required. The valve body adopts split type, and the seal of the two ends of the valve shaft is controlled by the rotating base surface between the butterfly plate and the valve seat and the fluoro rubber; and the valve shaft is not in contact with the fluid medium in the cavity. Pneumatic lining PTFE butterfly valves are widely used in the transportation of liquids and gases (including steam) in various types of industrial pipelines. There are occasions where severe corrosive media are used, such as: sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, alkali, and king Water and other highly corrosive media.
Fully lined with PTFE (F4), polychlorotrifluoroethylene (F3) and polyfluorinated ethylene propylene (F46) fluorine plastic lining butterfly valves, with corrosion resistance, no leakage, long life and other advantages. Lined PTFE pneumatic butterfly valve is suitable for concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, aqua regia, various organic acids, strong acids, oxidizing medium or high-temperature olefinic sulfuric acid, high temperature concentrated acetic acid, alternating acid and alkali and various organic solvents and other Strong corrosive media.
Pneumatic Fluorine Butterfly Valve main features:
1, small and lightweight, easy to disassemble and repair, and can be installed in any position.
2, the structure is simple, compact, 90 ° turn quickly open.
3, the operating torque is small, effortless and light.
4. The flow characteristics tend to be linear and the regulation performance is good.
5, sealing material, anti-aging, corrosion resistance, applicable to a variety of media.
