A fluorine lined ball valve is designed for use in corrosive environments, featuring a lining made of materials like PTFE (polytetrafluoroethylene) or PFA (perfluoroalkoxy). This valve provides excellent resistance to aggressive chemicals, ensuring reliable sealing and zero leakage. Key features include a full port design for minimal fluid resistance, making it suitable for on-off or control applications. The valve can handle a wide range of sizes (DN15 to DN350) and pressure ratings (Class 150 to PN40). Common applications include the chemical, petroleum, and pharmaceutical industries, where it effectively manages corrosive media.
