<\/p>\nPTFE butterfly valve is an industrial valve with polytetrafluoroethylene (PTFE) as the core material, designed for highly corrosive, high temperature, or high purity media environments. Its unique structure and material properties make it widely used in chemical, pharmaceutical, water treatment, food processing, and other industries, especially for occasions requiring strict sealing and chemical erosion resistance.<\/p>\n

Engineered with a soft-sealed structure and PTFE-lined components, this valve ensures superior corrosion resistance and long service life, making it ideal for water treatment systems, chemical processing, and general industrial fluid control.<\/p>\n Product Overview<\/h2>\nThe PTFE butterfly valve features a robust forged and welded valve body combined with a high-quality PTFE sealing surface. This design provides excellent sealing performance and durability under low-pressure working conditions.<\/p>\n With compatibility across multiple international standards such as JIS 10K, ANSI, and GB, the valve can be easily integrated into various pipeline systems. Its lightweight structure and easy operation make it a preferred choice for modern industrial piping solutions<\/a>.<\/p>\n Product Name: PTFE Butterfly Valve<\/p>\n<\/li>\n Working Temperature: -40\u00b0C to 120\u00b0C<\/p>\n<\/li>\n Work Pressure: Low Pressure (PN < 1.6 MPa)<\/p>\n<\/li>\n Seal Surface Material: Soft Sealed (PTFE)<\/p>\n<\/li>\n Valve Body: Forge Welding Structure<\/p>\n<\/li>\n Standards: JIS 10K, ANSI, GB<\/p>\n<\/li>\n Application: Industrial Usage, Water Treatment Systems<\/p>\n<\/li>\n \u041a\u043e\u0434 \u0422\u041d \u0412\u042d\u0414: 39209910<\/p>\n<\/li>\n Transport Package: Wooden Case<\/p>\n<\/li>\n<\/ul>\n The PTFE soft sealing surface provides excellent tightness and leak-proof performance. It ensures minimal leakage even after long-term operation, making the valve suitable for systems where sealing integrity is critical.<\/p>\n The low friction coefficient of PTFE also allows smooth opening and closing, reducing wear and extending the valve\u2019s service life.<\/p>\n |
