Abstract: This paper reports the results of a theoretical and experimental investigation to prove the effectiveness of an air inlet valve as a protection device against water hammer in delivery mains of pumping stations where, upon sudden stopping of pumps, cavitation conditions may occur close to the station. Theoretical research has proved that the valve, though simple and of very low cost, can considerably reduce pressure rise resulting from unsteady flow and the first experimental results fully confirm the forecasts of the theoretical model.
