The JL600-Q12 pneumatic thermal insulation jacketed ball valve has good thermal insulation and cold preservation characteristics, and the valve diameter is the same as the pipe diameter, and it can effectively reduce the heat loss of the medium in the pipeline. To transport high-viscosity media that solidifies at room temperature. According to the structure of the ball valve, the thermal insulation ball valve has several structural forms such as integral thermal insulation ball valve, two-piece thermal insulation ball valve, and wafer thermal insulation ball valve, which are widely used in urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection, etc. In the system pipeline of the industry.
