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.

We are good at making cast hand operated valve and forged ball valve with various special alloys, which are suitable for general working media such as water, solvent, acid and natural gas, as well as suitable for bad working.
