Use multiple control valves or multistage control valves so that the pressure drop happens gradually rather than all at once. This is called pressure drop staging. Place the control valve at a lower elevation in the system or in an area where the fluid temperature is reduced.
How can you avoid cavitation?
There are several ways you can avoid excessive cavitation. Here are a few of them: Make sure you select the right valve for your application. If your valves are the wrong size or the wrong style, their likelihood of cavitation increases. In water and liquid systems with high pressure drop, use an anti-cavitation valve.
