Design and selection of low noise control valve

The noise of most control valves occurs in the case of compressible fluid, because part of the energy is converted into sound during throttling... Generally, the measurement estimate is that if the product of Cv value and inlet pressure exceeds 1000, the control valve will generate a lot of noise under the critical pressure drop.

Cause and Prevention of Flash and Cavitation of Control Valve

Flashing refers to the phenomenon that when the static pressure from the constriction section to the valve outlet decreases to be equal to or lower than the saturated vapor pressure of the fluid at the valve inlet temperature after the incompressible fluid is throttled through the control valve, part of the liquid vaporizes to form gas-liquid two-phase flow behind the valve.
