Concealed rod structure, compact structure, space saving, with flange and threaded connections

Full bore design effectively eliminates pressure drop and eddy currents, slowing down the erosion of solid particles in the liquid on the valve

Metal seals are used between the valve cover and valve body, valve plate and valve seat, and valve body and valve seat

The surface of the valve plate and valve seat is sprayed (stacked) with hard alloy, which has good wear resistance and corrosion resistance

The valve cover and valve stem are designed with an inverted sealing structure, making it easy to replace the valve stem sealing ring under pressure

There is a sealing grease injection valve on one side of the valve cover to supplement the sealing grease, improve the sealing performance and lubrication of the valve plate and valve seat
