Fully welded pipeline ball valves have the advantages of fast opening and closing, small flow resistance, compact structure, light weight and reliable sealing. They are the preferred control components for long-distance pipelines such as oil, natural gas and refined oil to achieve gathering, distribution and other functions. There are generally two types of fully welded pipeline ball valves in terms of appearance and structural design, namely the spherical fully welded valve body structure and the cylindrical fully welded valve body structure.
