Jacketed insulation straight-through globe valve is mainly used in the system pipeline of chemical, petroleum, pharmaceutical, metallurgical and other industries, and its main function is to transport the medium that will solidify and be easy to crystallize at room temperature. A metal jacket is welded between the two flanges of the jacketed insulation straight-through globe valve, and a jacket interface is set on the side and bottom of the globe valve for injecting steam or other thermal and cold insulation media to ensure that the medium in the valve can work normally. The connection flange of jacketed insulated in-line globe valves is one to two specifications larger than that of ordinary globe valves.
