Product Description
The PTFE Lined Butterfly Valve is specially designed for corrosive media and demanding chemical processing applications. The fully lined PTFE body isolates the valve body from the process fluid, providing exceptional corrosion resistance and extended service life. A precision-molded PTFE seat with a Viton backup ring ensures bubble-tight shut-off and zero shaft leakage. Suitable for manual or automated operation, this valve is widely used in chemical, pharmaceutical, water treatment, food processing, and other industrial applications requiring reliable flow isolation.
