Air Release Valve / Air Valve

Based on the image, the object is an air release valve used in plumbing or irrigation systems.Function: This valve automatically removes trapped air pockets from piping systems to ensure smooth fluid flow and prevent damage.Mechanism: It operates automatically; when water fills the system, a float rises to close the valve, and it opens to allow air intake or release during pressure changes.Applications: These are commonly installed at high points in irrigation networks or water supply lines to prevent negative pressure and vacuum suction.
