1.Full-bore design effectively eliminates pressure drop and eddy currents and slows down solid particles in the fluid
flushing of valves;
2.Unique sealing design, so that the switching torque is greatly reduced;
3.Metal seals are made between the bonnet and the valve body, the valve plate and the valve seat ring;
4.Metal sealing surface spray (overlay) welding cemented carbide, with good wear resistance, corrosion resistance;
5.The seat ring is fixed by the fixed plate to maintain good stability;
6.The stem is equipped with an inverted sealing mechanism to facilitate the replacement of the stem sealing ring with pressure.
