Manual Lining Fluorine Butterfly Valve

Using the middle line fluorine structure. The valve body and valve plate are lined with PTFE or F46 and other strong corrosion resistant materials, can effectively avoid the corrosion of the valve with strong corrosive medium, and has good sealing performance. This series of butterfly valves are mainly used in chemical industry and other industrial processes of corrosive fluid control is to adjust or cut off a variety of chemical corrosive media ideal solution.
