1、 Overview of Pneumatic Insulated Ball Valve Products
The BQ641PPL/H pneumatic insulated ball valve produced by Shanghai Yuhu Company has good insulation and cooling characteristics, and the diameter of the jacket insulated pneumatic ball valve is consistent with the pipe diameter, while effectively reducing the heat loss of the medium in the pipeline. Pneumatic insulated ball valves are mainly used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, and food industries to transport high viscosity media that solidify at room temperature. Due to its integral structure, the pneumatic insulated ball valve has a smaller volume, lighter weight, no leakage, and good sealing performance compared to general ball valves. The jacket is welded with carbon steel pipe, which is more pressure resistant and firm than cast ones.
