 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.

 Engineered for demanding industrial environments, our 6-inch PTFE lined wafer butterfly valve provides exceptional resistance against highly corrosive media. This wafer type valve features a high-grade Alloy 20 disc combined with a chemical-resistant PTFE seat, ensuring longevity and reliable sealing performance in severe applications, such as chemical processing, water treatment, and pharmaceutical industries.

Designed for efficiency and ease of operation, this 150LB butterfly valve is equipped with a high-torque worm gear operator, allowing for precise flow control and manual handling. The compact, lightweight wafer-style body allows for quick, space-saving installation between standard pipe flanges without compromising structural integrity. Each unit undergoes rigorous testing to meet international quality standards, ensuring leak-free operation even in the most challenging process conditions.
