Manual PTFE Fluorine lined Wafer Butterfly Valve
Chlorine and liquid chlorine fluorinated butterfly valves are suitable for chlorine, liquid chlorine, acid and alkali and other corrosive media. The valve adopts a fluorine-coated butterfly plate with a spherical sealing surface, and a valve seat base silicone rubber gasket adjusts the sealing performance of the valve. When the valve body of the small-diameter lining fluorine Butterfly Valve is molded, the mating surface with the butterfly plate is designed as a spherical protrusion so that an interference fit is formed to form a seal. It is mainly used for quick cutting or adjusting flow.
Rubber lined butterfly valve is suitable for corrosive media such as chlor-alkali, chemical plant acid and alkali, salt water. Body material Ductile iron lining NBR, etc., the disc can be lining or not, the material is ductile iron.
