Three eccentric butt clip hard seal butterfly valve closes, the sealing ratio pressure between the two sealing surfaces of the sealing vice not only eliminates the conventional eccentric butterfly valve sealing ratio pressure reduction and disappearance, but also change the external driving torque to realize the sealing ratio pressure of its arbitrary adjustment, so it is widely used in medium temperature ≤ 425 ° C in the treatment of gold, electric power, petrochemical industry, as well as drainage and municipal construction of the industrial pipeline.

Fully lined fluorine butterfly valves are widely used in anti-corrosion pipeline systems. Mainly used to achieve the opening, closing, and adjustment of valves. Fully lined PTFE (F4), PTFE (F3), and PTFE (F46) fluoroplastic lined valves have the advantages of corrosion resistance, no leakage, and long service life. Suitable for concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, aqua regia, various organic acids, strong acids, oxidizing media or high-temperature sulfuric acid, high-temperature concentrated acetic acid, acid-base alternation, various organic solvents and other strongly corrosive media.

Fully lined fluorine butterfly valve has excellent anti-corrosion performance and can be applied to any concentration of acid, alkali, salt, oxidant, reducing agent, organic solvent, etc. It has the advantages of corrosion resistance, no leakage, and long service life. Suitable for concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, aqua regia, various organic acids, strong acids, oxidizing media or high-temperature sulfuric acid, high-temperature concentrated acetic acid, acid-base alternation, various organic solvents and other strongly corrosive media.
