Control Valve Sizing For Steam Systems | Spirax Sarco It is usually considered that the control valve will produce unacceptable noise if the velocity of dry saturated steam in the control valve outlet is greater than 0.3 Mach. The speed of sound in steam will depend upon the steam temperature and the quality of the steam, but can be calculated from Equation 6.4.2 if the conditions are known (Mach 1 = speed of sound). TOTAL HEAD, N.P.S.H. AND OTHER CALCULATION EXAMPLES ... To calculate the pressure head drop across the check valve we use the CV of the valve.
