The closing component of a track ball valve is a ball that rotates around the centerline of the valve body to achieve opening and closing. Track ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of media, and are one of the commonly used new types of valves.

Characteristics of track ball valve products：1. Open and close without friction. This function solves the problem of valve sealing being affected by friction between sealing surfaces，2. Top mounted structure. Valves installed on pipelines can be directly inspected and repaired online. Can effectively reduce device downtime and lower production costs，3. Single seat design. Eliminated the problem of abnormal pressure rise in the valve chamber medium affecting safety during use

4. Low torque design. The valve stem with a special structural design can be easily opened and closed with just a small handwheel valve，5. Wedge shaped sealing structure. Valves are sealed by the mechanical force provided by the valve stem, which presses the ball wedge onto the valve seat. Ensure that the sealing performance of the valve is not affected by changes in pipeline pressure difference, and that the sealing performance is reliable under various working conditions，6. Self cleaning structure of sealing surface. When the sphere tilts away from the valve seat, the fluid in the pipeline will pass uniformly along the sealing surface of the sphere at a 360 ° angle. Not only does it eliminate the local flushing of high-speed fluid on the valve seat, but it also washes away the accumulated substances on the sealing surface, achieving the purpose of self-cleaning.
