Product Overview
The CARX compound air release valve has a cylindrical barrel-shaped body. Its internal parts include a stainless steel float, a lever, and a disc. This valve is installed at the pump outlet or in water distribution pipelines to remove air accumulated in the pipeline, thereby improving the efficiency of the pipeline and the pump. Once negative pressure occurs in the pipeline, the valve rapidly draws in outside air to prevent the pipeline from being damaged by negative pressure. When water begins to fill the pipeline, the disc is in the open position for large-volume air discharge. When the air is exhausted and the valve is filled with water, the float rises and drives the disc to close, stopping air discharge. During normal water transmission, if a small amount of air accumulates inside the valve to a certain extent, the water level inside the valve drops, and the air is discharged through a small orifice. When the pump stops and the pipeline becomes empty or negative pressure occurs, the plug opens rapidly and draws in air, ensuring pipeline safety.
