Also known as thermal insulation jacket ball valve, ball valve on the basis of in welding metal jacket, used to inject steam or other heat, cold medium, the medium to ensure the valve to work properly. Insulation ball valve structure according to different, there are integral insulation ball valve, two-piece insulation ball valve, ball valve on preservation of several clip-on structure, thermal insulation ball valve with good cold properties, with the valve pain in the same diameter and diameter, while the media can effectively reduce heat loss in the pipeline. Mainly used in petroleum, chemical, metallurgical, pharmaceutical, food and other types of systems to transport will be solidified at room temperature but also high-viscosity media.

Ball has good heat insulation, cold properties, in addition to reducing diameter insulation valve, the valve diameter and the diameter of one to the medium linear flow resistance, can effectively reduce the heat loss of the media in the pipeline, therefore, solidification of easy, high-viscosity liquids with excellent performance. In addition to two-piece insulation valve, the ball valve design used in the entire overall style jacket, more uniform heat, cold. Jacket, with the jacket over the outer body welding, steam or cold water to allow the maximum pressure 1MPa.
