Gate Valve

The metallic seals are used between the valve deck and valve body, valve plate and valve seat.

The surface of the valve plate and valve seat is coated with the cemented carbide by spray (bead) welding, characterized by superior wear resistance and corrosion resistance features

The application of FB. Design is able to effectively eliminate the pressure drop and eddy flow and retard the impact of solid particles in the flow on the valve

The valve deck and valve rod are designed with the inverted sealing structure, which is facilitated to replace the valve rod sealing ring.

One side of the valve wall is designed with the sealing grease injection valve in order to complement the sealing grease, improve the sealing and lubricating properties of valve plate, valve seat.
