Air release valves are used mostly to expel pockets of air at system start up but as shown in the diagram above they are also used in conjunction with vacuum breakers to eliminate siphon in piping systems.

These valves are perfect for quickly venting large volumes of air during filling or startup.
It can be damaged keep the valve away from excessive heat or fire.
General operating instructions do not step on or apply excessive weight on air release valve.
Depending on the valve and the size of the vent aavs can support one or multiple vent lines.
Potable water and recycled water facilities.
Air release valves or air relief valve function to release air pockets that collect at each high point of a full pressured pipeline.
Air release valves are ideal for any type of closed loop or pressurized piping that can entrap air.
Air release valves protect the pipeline system and maintain its efficiency.
Apco s years of experience have proven almost without exception that the cost of air valves is less than one percent of the total installed pipeline cost.
An air release valve can open against internal pressure because the internal lever mechanism multiplies the float force to be greater than the internal pressure.
They also allow air back into the pipeline during emptying.

These valves are gravity operated devices that respond to the negative pressure of draining water and open to let air in.
It can be damaged or destroyed always operate the valve within the pressure vs.
