The top entry ball valve is designed as an integrated valve body. Its support and ball rod fixed by an upper-assembled pivot and an integrated pivot respectively and the integrated high-strength ball rod ensure an accurate ball positioning. The unique technology of retractable valve seat is adopted, realizing online replacement of valve stem, valve stem seal rings, metal valve seats and preloaded springs. The top entry ball valve is mainly used in pipeline and industry system and it has a top entry and on line maintenance function. It has a lot of advantages, such as small fluid resistance, simple structure, small volume, light weight, reliable sealing, convenience for operation and maintenance, open and shut quickly, as well as starts and closes flexibly.
