Overview:

The CARX composite air release valve consists of a main valve and a micro air release valve. This valve is installed at the highest point of the pipeline (a sealed air area) to improve the efficiency of water conveyance in the pipeline. When negative pressure occurs inside the pipeline, the valve quickly intakes air to prevent damage caused by negative pressure. When the pipeline is filled with water, the main valve releases a large amount of air and closes after the air is discharged. When a small amount of gas accumulates in the water flow inside the pipeline to a certain extent, the micro air release valve starts to release air to prevent gas layering in the pipeline, which would affect water flow efficiency. It can be customized according to different needs.
