BQ41F Insulated ball valveDetailed product description：

BQ41F ball valve has good insulation and cooling characteristics, and the valve diameter is consistent with the pipe diameter, while effectively reducing the heat loss of the medium in the pipeline. Mainly used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, and food to transport high viscosity media that solidify at room temperature. Due to its integral structure, the BQ41F ball valve is smaller, lighter in weight, and has no leakage, with good sealing performance. The jacket is welded with carbon steel pipe, which is more pressure resistant and firm than cast ones.
