Fluorine-Lined Flange Ball Valve

Product Overview

The Fluorine-Lined Flange Ball Valve is a highly corrosion-resistant valve designed for handling aggressive, corrosive, and high-purity chemical media. The valve features a full fluoropolymer (PTFE, PFA, FEP) lining on the body and ball surfaces, protecting the metal from chemical attack while ensuring smooth operation and tight shut-off.

Its flanged connection allows for robust and secure pipeline installation, while the ball valve design provides fast, reliable on/off operation and minimal pressure drop. This type of valve is widely used in chemical processing, pharmaceutical, water treatment, and other industries where corrosive media handling is critical.
