overview :Double eccentric structure design is adopted on the high performance butterfly valve. In the design, the spindle offsets the center of the seal face to form the first eccentric and thespindle offsets from the center line of the pipelineto form the second eccentric. The combination of two eccentric will generate cam effect as the disc screw in or out, making it possible to separate the disc from seat by very small torque. There is almost no friction between the disc and seat during switches, and that will lower the operation torque and extend service life. With these advantages, high performance butterfly valve can be used for various kinds of working conditions and medium.
