China Fluorine Lined Butterfly Valve

In the well-known butterfly valve technology, fluorine lined butterfly valve sealing form mostly adopts a sealing structure, and the sealing material is rubber, polytetrafluoroethylene, etc. Due to the limitation of butterfly valve structural characteristics of the fluorine lined butterfly valve, it is not suitable for industries such as high-temperature resistance, high-pressure resistance, corrosion resistance, and wear resistance.

Fluorine Lined Butterfly Valve vs. Triple Eccentric Butterfly Valve

An existing more advanced butterfly valve is a triple eccentric metal hard-sealed butterfly valve, the fluorine lined butterfly valve body, and the valve seat are connected components, and the sealing surface layer of the valve seat is welded with temperature-resistant and corrosion-resistant alloy materials. The multi-layer soft laminated sealing ring is fixed on the fluorine lined butterfly valve plate. Compared with the traditional butterfly valve, fluorine lined butterfly valve has high-temperature resistance, is easy to operate, and has no friction when opening and closing. When closing, the torque of the transmission mechanism increases to compensate for the sealing, which improves the butterfly valve. The advantages of sealing performance and extended service life. This type of valve should generally be installed horizontally in the pipeline.

FAQs of Fluorine Lined Butterfly Valve

  • Q How does a fluorine-lined butterfly valve work?

    A fluorine-lined butterfly valve operates by rotating a disc within the valve body to either allow or restrict the flow of fluid. The fluorine lining ensures that the valve can handle aggressive chemicals without corroding.

  • Q What are the benefits of using a fluorine-lined butterfly valve?

    • Chemical resistance: Ideal for handling aggressive chemicals and corrosive fluids.

    • Low friction: The smooth surface of the fluorine lining reduces friction and wear.

    • Durability: Enhanced lifespan due to resistance to corrosion and chemical attack.

    • Versatility: Suitable for a wide range of applications in various industries.


  • Q In which industries are fluorine-lined butterfly valves commonly used?

    • Chemical processing: For handling corrosive chemicals.

    • Pharmaceuticals: In processes involving reactive substances.

    • Food and beverage: For sanitary applications requiring non-reactive surfaces.

    • Water treatment: In systems dealing with aggressive or corrosive water types.


  • Q What types of fluorine linings are used in butterfly valves?

    • PTFE (polytetrafluoroethylene): Commonly known as Teflon, offers excellent chemical resistance and temperature tolerance.

    • FEP (fluorinated ethylene propylene): Similar to PTFE but with better formability.

    • PFA (perfluoroalkoxy): Combines the properties of PTFE with improved mechanical strength.


  • Q What should be considered when selecting a fluorine-lined butterfly valve?

    • Chemical compatibility: Ensure the fluorine lining material is compatible with the fluid being handled.

    • Pressure and temperature ratings: Verify that the valve can withstand the operating conditions of the system.

    • Size and type: Choose the appropriate valve size and actuation type (manual, electric, pneumatic) for your application.
