How can we reduce process noise, flashing and vibration in control valve ?

Kindly refer to folowing technical sheet explain exactly the causes of noise, flashing and vibration in control valve and how to reduce it.

Valves: Noise Calculation, Prediction, and Reduction

changing the valve with a higher nominal bore will reduce the effect, in case we still face the flashing in the simulation it's better to change the valve location if possible to get a longer straight run, in case we still get the flashing a special trim (v-port and hastelloy trim)
