Cast steel flanged PFA lined ball valve with lever PN16 is a corrosion-resistant isolation valve designed for aggressive chemical and highly corrosive fluid applications. The cast steel body (typically WCB or equivalent) provides robust structural strength, while the PFA lining (perfluoroalkoxy) offers exceptional chemical inertness, non-stick properties, and resistance to virtually all acids, solvents, and caustics . The flanged ends comply with PN16 (16 bar / 232 psi) standards, ensuring secure, leak-proof connections. Featuring a lever-operated, quarter-turn ball mechanism, this valve enables quick, reliable shut-off. The PFA lining is applied to all wetted parts, including the ball and seat, providing complete isolation of the metallic body from corrosive media . These valves are widely used in chemical processing, pharmaceutical, acid handling, and semiconductor industries .
