Technical Info
Product Overview
Brass air release valves are automatic venting devices designed to remove trapped air or gas from liquid piping systems. Installed at high points within pipelines, they help prevent air locks, ensure smooth fluid flow, improve system efficiency, and reduce noise and vibration.
Working Principle
Automatic air release valves operate through an internal float mechanism. When air accumulates in the valve chamber, the liquid level drops, causing the float to descend and open the vent. Air is released until liquid reenters the chamber, lifting the float and closing the vent to prevent fluid loss. This automatic cycle continuously expels trapped air without external control.
