Industrial-process control valves - Part 2-1: Flow capacity - Sizing equations for fluid flow under installed conditions

Industrial-process control valves - Part 2-1: Flow capacity - Sizing equations for fluid flow under installed conditions

Includes equations for predicting the flow of compressible and incompressible fluids through control valves. They are not intended for use when non-Newtonian fluids, fluid mixtures, slurries or liquid-solid conveyance systems are encountered. The equations for compressible fluids are for use with gas or vapour and are not intended for use with multiphase streams such as gas-liquid, vapour-liquid or gas-solid mixtures.

Industrial-process control valves - Part 8-4: Noise considerations - Prediction of noise generated by hydrodynamic flow
SIST EN 60534-8-4:2016

IEC 60534-8-4:2015 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 acoustics, fluid mechanics, and mechanics. The method is validated by test data. This third edition cancels and replaces the second edition published 2005. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Hydrodynamic noise is predicted as a function of frequency and b) Elimination of the acoustic power ratio.

Industrial-process control valves - Part 8-2: Noise considerations - Laboratory measurement of noise generated by hydrodynamic flow through control valves
SIST EN 60534-8-2:2012

IEC 60534-8-2:2011 includes the method for measuring the sound pressure level due to liquid flow through a control valve and the method for determining the characteristic increase of noise due to the onset of cavitation. It also defines the equipment, methods and procedures for the laboratory measurement of the airborne sound needed to determine these characteristics. Two methods are provided for testing the noise generating characteristics of control valves. The first is a uniform method of measuring the radiated noise from the valve and the associated test piping including fixed flow restrictions through which the test fluid (water) is passing. The second is a procedure for measuring the sound pressure levels within pipe systems upstream and downstream of the valve under fixed operating conditions. This second edition cancels and replaces the first edition published in 1991 and constitutes a technical revision that includes internal noise measurement.

Industrial-process control valves - Part 2-1: Flow capacity - Sizing equations for fluid flow under installed conditions
SIST EN 60534-2-1:2011

IEC 60534-2-1:2011 includes equations for predicting the flow of compressible and incompressible fluids through control valves. The equations for incompressible flow are based on standard hydrodynamic equations for Newtonian incompressible fluids. They are not intended for use when non-Newtonian fluids, fluid mixtures, slurries or liquid-solid conveyance systems are encountered. The equations for incompressible flow may be used with caution for non-vaporizing multi-component liquid mixtures. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. It includes the following significant technical changes with respect to the previous edition: - the same fundamental flow model, but changes the equation framework to simplify the use of the standard by introducing the notion of Δpsizing; - changes to the non-turbulent flow corrections and means of computing results; - multi-stage sizing as an Annex.

Industrial-process control valves - Part 8-3: Noise considerations - Control valve aerodynamic noise prediction method
SIST EN 60534-8-3:2011

IEC 60534-8-3:2010 establishes a theoretical method to predict the external sound-pressure level generated in a control valve and within adjacent pipe expanders by the flow of compressible fluids. This method considers only single-phase dry gases and vapours and is based on the perfect gas laws. It is assumed that the downstream piping is straight for a length of at least 2 m from the point where the noise measurement is made. The method is applicable to the following single-stage valves: - globe (straight pattern and angle pattern), - butterfly, - rotary plug (eccentric, spherical), - ball, and - valves with cage trims. Specifically excluded are the full bore ball valves where the product FpC exceeds 50 % of the rated flow coefficient. This third edition cancels and replaces the second edition published in 2000. This edition constitutes a technical revision. The significant technical changes with respect to the previous edition are as follows: - predicting noise as a function of frequency; - using laboratory data to determine the acoustical efficiency factor.

Industrial-process control valves - Part 7: Control valve data sheet
SIST EN 60534-7:2011

IEC 60534-7:2010 provides a list of requirements that are necessary for the procurement of the majority of control valves for process systems. The list is arranged to assist the specification writer with a standardized presentation of data and also to be a basis for use with data processing facilities. A detailed set of instructions is included in order to ensure that the abbreviated terms are fully understood and that consistent data entries are always made. This second edition cancels and replaces the first edition published in 1989. This edition constitutes a technical revision The main changes with respect to the previous edition are: - the standard has been updated to reflect digital electronic accessories and fieldbus protocols; - to aid clarification, the explanation of terms and definitions contains the same subheading as the information required in the control valve data sheet; - the column numbering system has been replaced with descriptive title headings.
