JACKET BALL VALVEThe jacket ball valve has such features as small fluid resistance, compact structure, light weight, good heat and cold insulation performance, flexible opening and closing. The jacket ball valve adopts the integral structure, so it is much smaller than the ordinary ball valve, and its weight is much lighter with good sealing performance. The media that are allowed to pass the jacket include 1MPa steam or cooled water, or special design can be made according to user requirements. It is mainly used in various systems in petroleum, chemical industry, metallurgy, pharmacy, food and other industries for transporting media of high viscosity that will be solidified under normal temperature.
