 Products Advantages :

PTFE butterfly valve valve is a soft sealing seat material commonly used in valves. It is commonly known as the "King of Plastics" and its called  PTFE  butterfly valve "Teflon". It is a polymer compound formed by polymerizing tetrafluoroethylene. It has excellent chemical stability and corrosion resistance. PTFE  butterfly valve one of the best corrosion-resistant materials in the world today. In addition to molten metal sodium and liquid fluorine, it can withstand other All chemicals will not change when boiled in aqua regia. are   PTFE  butterfly valve widely used in various applications that require resistance to acids, alkalis and organic solvents, sealing properties, high lubrication and non-stickiness, electrical insulation and good anti-aging endurance, and excellent temperature resistance (can Long-term operation at temperatures from +250°C to -180°C.

20 alloy Disc 20 alloy material butterfly valve wafer type gear operatedvalves have excellent corrosion resistance, good resistance to oxidative and moderate reductive corrosion, excellent resistance to stress corrosion cracking and good local corrosion resistance, and are satisfactory in many chemical process media. Corrosion resistance properties. The applicable media for the No. 20 alloy valve include highly corrosive inorganic acid solutions, various media containing chlorides, formic acid and acetic acid, acid anhydrides, seawater and salt water, etc.
