First, the pneumatic lining fluorine flange butterfly valve product overview

Pneumatic fluorine fluorine butterfly valve with a spherical sealing surface of PTFE-lined butterfly plate, pneumatic fluorine fluorine butterfly valve operation light, tight sealing performance, long service life; can be used for rapid cut off or regulate the flow of use. Pneumatic butterfly valve PTFE lining is required for reliable sealing and good regulation of the occasion. The valve body adopts the split type, and the seal at the two ends of the valve shaft is controlled by the fluorinated rubber on the rotating base surface between the valve disc and the valve seat; the valve shaft is not in contact with the fluid medium in the cavity. PTFE pneumatic butterfly valve is widely used in various types of industrial pipes in the liquid and gas (including steam) transport, the use of serious corrosive media, such as: sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, alkali, Wang Water and other media with strong corrosive. 
 
 Fluoride-lined butterfly valve with PTFE, FFC, F46 and Fluoroplastics lined butterfly valves with corrosion resistance, no leakage and long service life. Lined PTFE pneumatic butterfly valve for concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, aqua regia, a variety of organic acids, acid, oxidizing medium or high temperature olefin acid, high temperature concentrated acetic acid, acid and alkali alternating and a variety of organic solvents and other Strong corrosive media. 
 
 Pneumatic fluorine butterfly valve main features: 
 1, small and lightweight, easy disassembly and maintenance, and can be installed in any location. 
 2, the structure is simple, compact, 90 ° turn quickly open. 3 
 3, operating torque, light and labor-saving. 
 4, flow characteristics tend to be straight, good performance. 
 5, sealing material aging resistance, corrosion resistance, applicable to a variety of media.
