The valve is used in three-dimensional eccentric principles of design, so that the sealing surface of the space trajectory to reach the ideal, no friction between the seal faces to each other, without interference, coupled with the sealing material is properly selected so that the valve sealing, corrosion resistance, high temperature resistance and wear resistance has been a reliable guarantee.
Its main features are as follows:
1, the operating torque is small, easy to operate, saving smart;
2, three-dimensional eccentric structure, the disc more closed more tight, reliable sealing performance, zero leakage;
3, high pressure, corrosion resistance, wear resistance, long service life.
