The insulation ball valve has good thermal insulation and cooling characteristics, and the diameter of the valve is the same as that of the pipe. At the same time, it can effectively reduce the heat loss of the medium in the pipeline. Mainly used in petroleum, chemical industry, metallurgy, pharmacy, food and other systems to transport high viscosity medium that will solidify at room temperature. This kind of valve is a top-mounted structure, which can effectively reduce the shutdown of the device, reduce the cost, and design a single valve seat, eliminating the safety problem due to abnormal pressure rise of the medium in the valve chamber。
