Pneumatic Triple-Eccentric Hard-Seal Butterfly Valve

This valve adopts a “triple-eccentric” structure (the axes of the valve stem, disc sealing surface and valve body sealing surface are offset from each other), and is equipped with a pneumatic actuator with a manual emergency handwheel. The hard-seal design gives it the characteristics of high temperature resistance, wear resistance and tight sealing. It can not only cut off fluid quickly, but also adjust flow precisely, and is widely used in high-temperature, high-pressure and strong-corrosion industrial pipeline systems in petroleum, chemical, metallurgical and other fields.
