Ball valve is a valve whose opening and closing parts (balls) are driven by a valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. It only needs to be operated with a rotation of 90 degrees and a small torque to close tightly. Ball valves are most suitable for switching and shut-off valves
With the continuous improvement of production technology and product structure, ball valves have rapidly developed into a major type of valve, and the use of ball valves is increasing year by year.
