The QB2 dual-port exhaust valve is large in size, heavy in weight, and small in displacement. QB2 double port exhaust valve was the most ideal product in the late 1980s and has been continuously used since its introduction. The exhaust valve is a necessary equipment for the pipeline. It is installed at the highest point of the pipeline or at a closed air place to remove the gas in the pipeline, to clear the pipeline, and make the pipeline run normally.
