Gate valves perform an important function in different industries that have extensive use of liquids in their day to day operation. this makes it imperative for them to select a  that can handle the pressure, withstand fluctuating temperatures, and is resistant to rust and other wear and tear issues.

Characteristics and features

the metallic seals arc 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(Full-bore design). 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 seal.

Can be equipped with a variety of specifications of pneumatic (hydraulic) actuators according to user requirements.
