Air valves are normally required on piping systems, for example, offshore fire fighting systems, to vent air from a pipeline/riser on pump start-up and admit air back into the system under vacuum conditions. Often they are overlooked, yet play a crucial role within a pipe/pump system. It is important that they are correctly specified with their function, size and location to help in ensuring that the system is operating efficiently.
