DN150 PTFE Lined Butterfly Valve – Corrosion-Resistant Valve for Chemical Processing Systems

✅ The DN150 PTFE Lined Butterfly Valve is specifically designed for isolating and regulating the flow of corrosive fluids in industrial piping systems. Featuring a PTFE (Teflon) liner that completely isolates the valve body from the process media, it provides outstanding resistance to aggressive chemicals while ensuring long service life and reliable sealing performance.

✅ The valve operates with a quarter-turn disc mechanism, allowing fast opening and closing, low operating torque, and compact installation. This design minimizes pressure loss while providing efficient flow control in medium and large-diameter piping systems.

✅ The PTFE lining offers exceptional chemical resistance against sulfuric acid, hydrochloric acid, nitric acid, caustic solutions, organic solvents, and many other aggressive industrial chemicals. Its low-friction surface also reduces media adhesion and ensures smooth valve operation over extended periods.

✅ The valve body is typically manufactured from ductile iron or cast iron for excellent mechanical strength, while the disc is available in stainless steel or PTFE-coated construction for enhanced corrosion resistance. A stainless steel shaft combined with high-quality sealing components provides reliable leak-tight performance.

✅ With a DN150 (6-inch) nominal size, this butterfly valve is suitable for high-flow applications in chemical processing plants, water treatment facilities, pharmaceutical manufacturing, food processing, and many other industrial sectors. It can be equipped with a lever handle, gear operator, pneumatic actuator, or electric actuator to meet different automation requirements.

✅ Combining excellent corrosion resistance, reliable performance, easy maintenance, and long operational life, the DN150 PTFE lined butterfly valve is an ideal solution for industrial systems handling aggressive fluids under demanding operating conditions.
