Air valves as a self-actuated valve play an important role which is venting of the trapped air in the main and supply lines. In these types of valves the fluid flow activates the venting operation. Large venting orifice allows large volumes of air to be released on start-up and enter the pipe for vacuum breaking on shut down. Small venting orifice allows air bubbles to be released under the fluid pressure.

It’s strongly recommended to install air valves in high points of pipeline, after pumps and control valves.
Also for flat pipelines it’s required to consider air valve in each 500 to 1000 meters.
