The full-bore design effectively eliminates pressure drop and vortex, and slows down the erosion of solid particles in the fluid on the valve.

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

Hard alloy is sprayed (stacked) welded on the surfaces of the valve plate and valve seat, which has excellent wear resistance and corrosion resistance.

The valve cover and valve stem are designed with an inverted sealing structure, which facilitates the replacement of the valve stem sealing ring under pressure.

A sealing grease injection valve is provided on one side of the valve cover to replenish the sealing grease and improve the sealing performance and lubrication performance of the valve plate and valve seat.
