Insulation jacket ball valve is mainly used in the petroleum, chemical, metallurgy, pharmaceutical, food and other kinds of systems, to transport under normal temperature solidification of heavy oil, high viscosity medium glue etc..
Product features:
■ insulation jacket ball valve adopts an integral jacket structure design, more uniform heat, cold, heat insulation ball valve than smaller volume, lighter weight, and no leakage, good sealing performance, the use of carbon steel welded jacket casting more pressure than solid. Jacket, with the jacket over the outer body welding, high pressure steam or cold water to allow the 1MPa.
■ insulation ball valve has good thermal insulation, cooling characteristics, in addition to reducing diameter insulation valve, the valve diameter and the diameter of a to,
■ medium linear flow, small resistance, can effectively reduce the heat loss of the medium in pipelines, therefore, the liquid medium solidification of easy, high viscosity has excellent performance.
