Air release valves are designed to discharge air pockets from the pipeline in order to maintain efficient water flow.
Since air release valves have orifices that range in diameter from 1 16 of an.
These air valves will discharge air from a non pressurized pipe enabling the efficient filling of the pipeline.
Use this valve with oil diesel fuel gasoline and kerosene.
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.
Air release valves or air relief valve function to release air pockets that collect at each high point of a full pressured pipeline.

Also known as quick exhaust valves.
Air release valves vacuum valves air vacuum valve air release valve.
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.
Continuously release air from a pressurized system preventing the build up of air pockets in the pipeline and admit large amounts of air into the system when vacuum conditions occur protecting the pipeline.
The 90 elbow shape allows you to install them in tight spaces.
