Ball Valves

Ball valves are used to cut off or connect the medium in the pipeline, as well as to regulate and control the fluid. As a professional manual ball valve manufacturer, we can provide you with all kinds of floating and trunnion mounted ball valves.

Ball valves mainly feature compact structure and reliable sealing. The sealing surface and spherical surface are often closed, which means it\'s not easy to be eroded by medium and easy to operate and maintain.
