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

    Clean Water Air Release Valves should always be installed in a vertical position at high points of a pipeline. An isolation valve between this unit and the transmission (pipeline) system is recommended.
