The existence of cavitation in hydraulic equipment leads to inefficient operation, mechanical damage, and vibration. The performance of valves in fluid power control systems is affected by cavitation. The spool valve finds numerous applications in this field and it is essential that these effects be thoroughly understood. In this paper a study is made of the occurrence of cavitation and its effect on the discharge characteristics of spool valves.
It is shown that over a range of flow conditions cavitation has a profound effect on the flow coefficient.
