    Double eccentric structure design, to avoid the wear of the sealing surface, maintaining the integrity of the seal and high service life.
    Design of wide angle seat to avoid pressing and damaging the valve seat and valve tight contact, providing longer service life.
    Two – stage high – strength stem structure to ensure easy maintenance, double eccentric structure makes the online maintenance of the seat and disc becomes easy and fast.
    Internal stem / disc drive to avoid the pins or bolts installation may produce more leakage way.
    - flexible retaining ring on the valve flap provides a complementary seating pressure, not only has the advantages of simple structure and light weight, the driving torque is small, simple, rapid, good flow regulating function and close sealing characteristics.
