BQ71F wafer-type insulated ball valve
The BQ71F wafer-type insulated ball valve features excellent heat and cold insulation properties, and its valve diameter matches the pipe diameter, effectively reducing heat loss of the medium in the pipeline. It is mainly used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, and food industries to transport high-viscosity media that solidify at room temperature. Main models and insulated types: Manual (BQ71F), Pneumatic (BQ671F), Electric (BQ971F)
