The Bermad vacuum breaker air valve is for irrigation, designed to enable air intake and prevent the formation of negative pressure caused by line drainage. The ARV remains closed at positive pressure conditions.
Vacuum Breakers are necessary for drip irrigation systems that have drip tubes which which don’t feature anti-siphon technology.
