The use of air release valves in hydraulic pipelines is necessary and one of the most important safety elements in all water and irrigation installations.  Its main mission is to prevent negative pressures in the network and over pressures generated by the presence of air in the pipelines.  Compressed air can also trap energy in pipelines.
