How can Cavitation Damage be contained?

Control Valves
1

Three methods exist for treating cavitation in control valves

The first is to ensure that the plug and seat are made of a material that can resist the damage (e.g. stellite hard facing).

The second is to control where the bubbles collapse and keep this away from vulnerable components (see Cav Control trim).

The third is to control the pressure drop and velocities to ensure that the liquid pressure does not fall below the vapor pressure – thus eliminating cavitation altogether.

First and second point is clear, we are playing with valve so we can request vendor to do so.
But third point about controlling the pressure drop. How can we do it? Please guide
