Double eccentric structure design is adepted on the high perfomance uttrly valve. In the design, the spindle ofsets the center of the
seal face to form the first eccentric and the spindle offset from the center line of the pipeline to form the second eccentric. The combination
ofl two eccentric wl generate cam eflect as the disc screw in or out, making it possible to separate the disc from seat by very small torque,
There is almost no fition between the disc and seat during switches, and that will lower the operation torque and extend service ide Withthese advantages, high porformance buterly valve can be used for various kinds of working conditions and medium.
