Product features

The pneumatic insulation ball valve is especially suitable for liquid media that are easy to solidify and have high viscosity. It has good thermal insulation and cold insulation characteristics to prevent material crystallization from blocking the pipeline, especially in some occasions where the material is infrequently opened and closed, and the material fluidity is not very good. The jacketed insulation pneumatic ball valve has the same diameter as the pipe diameter, and can effectively reduce the heat loss of the medium in the pipeline.
Features of pneumatic insulation ball valve:
 
According to different operating conditions, the jacketing of pneumatic insulation ball valve can be condensed water, which is used to precipitate crystals due to overheating. It can also use hot water, steam and heat transfer oil as heat tracing. It has good thermal insulation and cold insulation characteristics, and is commonly used to transport high viscosity media that will solidify at room temperature.

Application of pneumatic insulation ball valve:
 
Pneumatic insulation ball valve is used to maintain a certain temperature, or it is easy to block the valve when the medium is cooled, and heat tracing insulation is required. For example, the thermal insulation of liquid flow is required to be 135-145 degrees, and liquid flow below the index will freeze. If the valve does not use steam jacket, it will cause the valve to be inoperable and can be used in petroleum, chemical, metallurgical, pharmaceutical, food and other systems.
