Forged Steel Cryogenic Ball Valve

The working principle of the forged steel ball valve is to rotate the valve stem to open or block the valve. It is usually a full-bore ball valve or a 90-degree angle switch. It is lightweight, small in size, can be made into a large diameter, has reliable sealing, simple structure, and easy maintenance. The sealing surface and spherical surface are always in a closed state and are not easily eroded by the medium. They are used in various industries. Be widely used.

The forged steel ball valve has a 90-degree rotation action. The plug body is a sphere with a circular through hole or channel passing through its axis. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small rotational torque to close tightly.
