Top entry type ball valve in the pipeline is simple and rapid demolition, maintenance convenient. When the valve in the pipeline fails to repair, do not have to remove the valve from the pipeline, just remove the flange bolts and nuts, the valve cover and stem assembly removed from the valve body, and then remove the ball and valve seat assembly. You can repair the ball and valve seat. This service saves time and minimizes production losses.
