Industrial-process control valves - Noise considerations. Prediction of noise generated by hydrodynamic flowWhat is BS EN 60534 8 4 Noise in control valves about? BS EN 60534 8 4 is a part of the IEC 60534 series. BS EN 60534 8 4 establishes a method to predict the noise generated in a control valve by liquid flow and the resulting noise level measured downstream of the valve and outside of the pipe. The noise may be generated both by normal turbulence and by liquid cavitation in the valve. Parts of the method are based on fundamental principles of
