This paper describes the results of a series of tests that were carried out to assess the erosion suffered by valves controlling sand-laden water. Two types of valves were tested: a fluidic non-moving-part valve and a rubber diaphragm valve. In each test two valves of the same type were arranged in series so that each handled the same flows but, because of the pressures in the system, the water in the second valve was cavitating. With only cavitation erosion the surface of the valve was merely discoloured. With particulate erosion in the non-cavitating flow there was some material removal by abrasion. With both cavitation and sand particles in the flow there was very considerable material removal, much more than would be expected from summing the two individual effects.
