Double-Clip Connected Ball Valve

Double-clip connected ball valve features

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.
