Product Overview
The PTFE / PFA Lined Gate Valve is specifically designed for highly corrosive media requiring reliable isolation and long-term chemical resistance.
All wetted parts of the valve—including the body cavity, gate, and sealing surfaces—are fully lined with PTFE or PFA, effectively isolating the metal body from aggressive fluids.
This valve is widely used in chemical processing, chlor-alkali systems, pharmaceutical production, acid and alkali pipelines, and corrosion-critical industrial applications.
