Pneumatic insulated ball valves offer excellent heat and cold insulation properties, and the passage diameter of jacketed insulated pneumatic ball valves matches the pipe diameter, effectively reducing heat loss of the medium in the pipeline. These ball valves are mainly used in various systems such as oil, chemical, metallurgy, and food industries for transporting high-viscosity media that solidify at normal temperatures. Due to their integrated structure, insulated ball valves are smaller and lighter than conventional ball valves, with no external leakage and excellent sealing performance. The jacket, made of carbon steel pipe焊接, is more pressure-resistant and sturdy than castings.
