With the design based on the fixed type, the upper part of top entry ball valves have bonnets, and spheres, sealing rings and valve seats are all installed from the top. The stem is connected with the sphere, eradicating the chance of loosening or being hauled out. It's easy to check and maintain top entry ball valves fitted on pipelines, which greatly saving time and cost. And they are mainly aimed at highly corrosive media.
