The Fluorine-Lined Ball Valve is a high-performance industrial valve engineered for corrosive media control, integrating the structural advantages of ball valves with the extreme corrosion resistance of fluoropolymer linings. Compliant with international standards (ANSI/ASME, ISO, GB, DIN), it features a metal valve body (WCB, stainless steel, cast iron) fully lined with fluoroplastics (PTFE/PFA/FEP) on the inner surface, ball, and valve seat—ensuring complete isolation between the medium and metal components.
