The double-clip connected ball valve possesses such features as compact structure, smaller volume, lighter conference, fine sealing performance, flexible on-off, convenient installation course, etc. The heating double-clip connected ball valve enjoys favorable heat/cold preservation performances, which not only prevent effectively the scabby medium in pipeline from solidifying but also reduce the heat loss of the medium in pipeline. The double-clip connected ball valve series could also be applied with the mounted corresponding motor or air operated plant to implement remote control or automatic control.
