    Performance: 

    ● The Air Release Valve is automatic in operation. They have much smaller orifices than Vacuum Valves. They release small pockets of air that gather at the high points of a system after it is filled and under pressure. 
    ● The Air Release Valve has the ability to open against internal pressure because it has a small orifice and a leverage mechanism that multiplies the force of the float.
    This force must be greater than the internal pressure across the orifice in order to open the orifice when a pocket of air needs to be vented

    The automatic exhaust valve is usually set at the highest point and local high point of the system’s piping, and is used to remove the air stored in the water pipeline.
