anaalmansuri,
1) Using multistage control valve
2) Using harder trim material

Also, increase the operating pressure, lower the elevation of the CV, decrease the operating temperature, add a downstream orifice, and/or use a drag valve (CCI).

Dear Analmansuri
Please check with control valve vendors, they have the type of valve that is using multiple-valves concept that eliminate cavitation problem. It is as though you are installing several valves in series.
