Why Choose PFA/PTFE Lined Flange Butterfly Valve?
Typical Applications
PTFE/PFA lined flange butterfly valve is a corrosion-resistant valve specifically designed for harsh working conditions. The core design is to fully liner a layer of high-performance fluoroplastic (PTFE or PFA) on key components such as the metal valve body cavity and butterfly plate. This lining completely isolates the metal valve body from corrosive media, making it an ideal choice for handling fluids such as strong acids and alkalis.
PTFE/PFA lined flanged butterfly valves are specially engineered for demanding services involving strong acids, caustic alkalis, toxic media, and ultrapure water. They are widely deployed in chemical processing, semiconductor manufacturing, pharmaceuticals, new energy, and environmental protection. These valves safely handle highly corrosive or high‑purity fluids, including concentrated sulfuric acid, hydrochloric acid, hydrofluoric acid, organic solvents, electrolytes, and ultrapure water. With bubble‑tight shut‑off, 180°C temperature resistance, low operating torque, and virtually maintenance‑free performance, they deliver reliable protection for critical process applications.
