Steel lined four-fluorine ball valve Q41F46-16C is a kind of corrosion resistance, acid and alkali resistance ball valve, mainly used in chemical, petroleum, pharmaceutical and other industries to control and regulate corrosive media. The ball valve is made of carbon steel cast steel material, lined with tetrafluoroethylene material, with high chemical stability and corrosion resistance, which can effectively prevent the corrosion and damage of the medium to the valve. The ball valve has the advantages of compact design, flexible operation and excellent sealing performance, which can completely cut off the medium flow and ensure the safe operation of the pipeline system. At the same time, the valve body is made of 304 stainless steel, which has good corrosion resistance and mechanical strength, and can adapt to various harsh working environments and conditions. The steel lined four-fluorine ball valve Q41F46-16C flange connection is DN200, suitable for most industrial piping systems. Its design meets international standards, reliable quality and long service life. In addition, the ball valve also has the advantages of simple maintenance, easy installation, etc., is an ideal valve choice in various chemical, petroleum, pharmaceutical and other industries.
