XF51 Triple Offset Butterfly Valve
XF51 Triple offset butterfly valve is adopted a muti-level triple offset metal seal structure, precision valve plate sealing surface after polishing combine with triple offset sealing surface, resistant to high temperature, high pressure, allowing the media have tiny particles, long service life and other characteristics. Bi-directional zero leakage, reliable sealing for high vacuum systems; self-tight sealing, ultra-low torque, rapid opening and closing effort; simple structure, small size, easy to maintain, easy to install; long life, suitable for frequent switching, durable; has lengthened precision composite bearings and stem anti-out safety design, is widely used in metallurgical, chemical, oil, combustible gas, drainage and other industries.
