First, the BQ41F insulation jacket ball valve features
 BQ41F shrinkage insulation ball valve with insulation, cold insulation properties. According to GB design and manufacture of flange connection by 79-94 standard for the manufacture of petroleum, chemical, metallurgical, pharmaceutical industry. 
 BQ41F shrinking ball valve insulation as a result of steam jacket insulation. So even if the outside temperature drops below zero, the valve is still flexible operation to ensure that the pipeline can be disconnected, the advantage of the general control valve does not have. It is the ideal control valve for heavy oil pipelines. 
 According to user needs jacket injection steam, thermal oil, cooling water, air conditioning and so on. Use the entire valve temperature or temperature to reach the desired temperature. To prevent the media crystallization. BQ41F shrinking insulation ball valve products have good insulation cold and cold characteristics, with the pain of the valve diameter and diameter of the same, but can effectively reduce the pipeline heat loss of medium. Mainly used in petroleum, chemical, metallurgy, pharmaceuticals, food and other systems to transport medium viscosity will be solidified at room temperature.
