Series War

Water Air Release Valves

AirPro Max® Series WAR Air Release Valves are designed to vent trapped air that collects at high points in a pipeline. These valves continuously release air from systems thereby preventing large air pockets to form, which can cause damaging pressure surge to the system. In installations lacking Air Release Valves, large pockets of air in the pipeline can cause increased power consumption, and decreased flow. Another potential result of excessive air accumulation is sudden pipeline rupture that is can be mistakenly attributed to ground settling or defective pipe.
