Insulation jacket ball valve has the advantages of good thermal insulation properties, and the valve diameter and the diameter of one to medium linear flow resistance is small, the liquid medium is most suitable for high viscosity, easy solidification. At the same time, it can effectively reduce the heat loss of the medium in the pipeline. The overall jacket design, more uniform insulation, cold preservation. The jacket and the outer side of the valve are welded with the jacket nozzle, allowing the maximum pressure of steam or cold water to be 1MPa. Mainly used in petroleum, chemical, pharmaceutical, food and other systems, in order to transport at room temperature will be solidified high viscosity medium.
