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.
