Product features

The pneumatic insulated ball valve is especially suitable for the liquid medium which is easy to solidify and has high viscosity. It has good heat preservation and cold insulation characteristics to prevent the material crystallization from blocking the pipeline, especially in some occasions where the material flow is not very good due to the infrequent switch. The diameter of the jacketed thermal insulation pneumatic ball valve is consistent with the pipe diameter, and can effectively reduce the medium heat loss in the pipeline.
Features of pneumatic insulated ball valve:
 
According to different operating conditions, the jacket of pneumatic insulated ball valve can be condensate, which is used to precipitate crystals due to overheating, and can also be used for heat tracing with hot water, steam and heat transfer oil. It has good heat preservation and cold insulation characteristics, and is commonly used to transport high viscosity media that will solidify at room temperature.

Application of pneumatic insulated ball valve:
 
Pneumatic insulated ball valve is used to keep a certain temperature, or medium cooling is easy to block the valve, heat tracing insulation. For example, the heat preservation requirement of the liquid flow is 135-145 degrees. If it is lower than the target, the liquid flow will freeze. If the valve does not use steam jacket, the valve will not be able to operate. It can be used in petroleum, chemical, metallurgical, pharmaceutical, food and other systems.
