Valve Noise Prediction vs. Velocity Head Limitations In ...
www.iceweb.com.authat having a trim exit velocity head lower than 480 kPa will still generate a very high valve noise level if the valve outlet Mach number is high. Noise Prediction in Control Valves The IEC 534-8-3 aerodynamic noise standard is the most widely used in the valve industry for noise prediction in control valves.
