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 manufacturer of customized valves, 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. NAI LOK is a professional ball valve supplier
and valve manufacturing company that has different types of ball valves for sale. 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.
