[product characteristics]
BQ41F type insulation ball valve has good insulation and cooling characteristics, and the diameter of the valve is consistent with the pipe diameter, but also can effectively reduce the heat loss of medium in the pipeline. It is mainly used in petroleum, chemical, metallurgical, pharmaceutical, food and other systems to transport high viscosity medium at room temperature. Because of the integral structure, the BQ41F ball valve is smaller, lighter and less leakage than the general ball valve, and the sealing performance is good. The jacket is welded by carbon steel pipe, which is more stable than the casting.
