[0002] Sealed ball valve is a valve whose opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. It 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 very small torque to close tightly. It is suitable for use as a switch or cut-off valve. Sealed ball valve is widely used in oil refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal administration, steel and other industries, and occupies a pivotal position in the national economy.
