The valve plate and sealing ring adopt a unique three eccentric structure, which has the characteristics of compact structure, good cutting performance and long service life. It has both adjustment and cutting functions. The actuator adopts high-performance double piston gear tooth strip structure or shift fork structure, with high transmission efficiency and compact structure.

The valve body adopts integral casting technology, with compact structure, small volume and light weight;

Three eccentric installation of valve plate. When closed, the valve plate expands outward to achieve the peripheral sealing state; When the valve is opened, the valve plate and the sealing ring are quickly separated to effectively prevent the wear of the sealing ring;

The valve seat and sealing ring adopt replaceable structural design to facilitate on-site maintenance and replacement;

When the sealing ring is in the form of multi-level sealing, there can be no leakage; In case of all metal hard seal, the leakage level is class V;

Due to the three eccentric structure, the operating torque is greatly reduced and the two-way zero leakage can be truly realized;

The flow resistance is small and the rated flow coefficient is large, which is about 3 times that of the single seat valve with the same diameter.
