First, Pneumatic Lining Fluorine Clip Butterfly Valve Products Overview
Pneumatic fluorine butterfly valve with a spherical sealing surface of the lining PTFE lining butterfly plate, pneumatic fluorine valve convenient operation, tight sealing performance, long service life; can be quickly cut off or adjust the flow of. Pneumatic lined PTFE butterfly valve is suitable for occasions requiring reliable sealing and good regulating characteristics. The valve body adopts split type, and the seal at both ends of the valve shaft is controlled by the rotary base plane between the butterfly plate and the valve seat with fluorine rubber, and the valve shaft is not contacted with the fluid medium in the cavity. Pneumatic PTFE lined butterfly valve is widely used in various types of industrial liquid and gas pipeline (including steam) transportation, there are serious corrosive media occasions, such as: sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, alkali, aqua regia and other strong corrosive media.
Totally lined polytetrafluoroethylene (F4), poly three fluoro vinyl chloride (F3) and poly (ethylene propylene glycol) (F46) fluoroplastic lined butterfly valve have the advantages of corrosion resistance, no leakage, long service life and so on. F-lined pneumatic butterfly valve used in concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, aqua regia, organic acid, strong acid, oxidizing medium or high temperature high temperature concentrated sulfuric acid, vinyl acetic acid, alkali alternate and various organic solvents and other corrosive media.
