DN200 Stainless Steel 316 PTFE Lined Butterfly Valve for Corrosive Media

✅ The Stainless Steel 316 PTFE Lined Butterfly Valve DN200 is designed for isolation and flow control of corrosive liquids, acids, alkalis, solvents, and other aggressive media in industrial piping systems. The combination of 316 stainless steel construction and PTFE lining provides excellent corrosion resistance, reliable sealing performance, and extended service life.

✅ With a DN200 (8-inch) size, this butterfly valve is suitable for medium and high-flow industrial pipelines. The wafer or lug mounting design allows quick installation between flanges while minimizing installation space.

✅ The PTFE liner offers outstanding chemical resistance and excellent sealing capability, preventing leakage and ensuring safe operation even in demanding process conditions.

✅ Both the valve body and disc are manufactured from 316 stainless steel, providing superior resistance to corrosion, oxidation, seawater, and a wide variety of industrial chemicals. Precision machining ensures smooth operation and reduced operating torque.

✅ The valve can be equipped with lever handle, worm gear operator, pneumatic actuator, or electric actuator, allowing manual or fully automated operation depending on system requirements.

✅ This butterfly valve is widely used in chemical processing, wastewater treatment, pharmaceutical production, food processing, paper manufacturing, electroplating plants, fertilizer production, and other industrial applications involving corrosive fluids.
