IEC 60534-7 pdf download – lndustrial-process control valves -Part 7: Control valve data sheet
This part of the IEC 60534 series provides a list of requirements that are normally necessary forthe procurement of the majority of control valves for process systems. No attempt is made toinclude all possible requirements for any conceivable process.
The list is arranged in a format designed to assist the specification writer with a standardizedpresentation of dalta and also to be a basis for use with data processing facilities.
Adetailed set of instructions is included in order to ensure that the abbreviated terms are fullyunderstood and that consistent data entries are always made.

3Terms and definitions
For the purposes of this document, the terms and definitions given in the lEC 60534 series apply.
The control valve data sheet (Figure 1 ) below may be used for three different levels of control valveselection.
4.2Preliminary valve specification
For a preliminary inquiry and/or quotation,buyer and vendor may agree on a minimum level ofinformation. In this case, the buyer and manufacturer mark a few lines only in column 1 by a dot,triangle or other symbol.This method minimizes efforts for both buyer and vendor.
4.3lnquiry valve specification
In inquiry stage, some of the process data and also some of the general requirements will not befully known and specified. This may not allow the application of the lEC calculation methodsgiven in IEC 60534-2-1 and IEC 60534-2-5.Preliminary valve sizing methods may be used at thisstage. Since the main focus of the inquiry specification is to provide all data required to work outa comparable technical and commercial quote, in most cases there is a need to mark additionallines beyond those in 6.1. Also on the inquiry specification, the lines in column 1 shall bemarked by a dot,triangle or other symbol by the buyer and manufacturer.
4.4Order valve specification
A complete ordering specification should ideally include all relevant information about the valve,actuator and accessories concerned. In this case,the fully completed control valve data sheetbecomes a kind of passport,which allows an exact identification and can be used for manypurposes.
5 General requirements sheet
5.1 Purpose of the general requirements sheet
The purpose of the general requirements sheet (Figure 2), which is optional, is to provide a meansfor the user to specify general or special requirements that are applicable to a valve or group ofvalves. Examples are national and international standards,user company standards and specialproject requirements. These general or special requirements shall be listed in the table of contentssection of page 1 of the general requirements sheet. Supplementary general requirements sheets(Figure 3) may be used as necessary. it may also be necessary to cross-reference the generalrequirements sheet(s) with the data sheets. if there is a conflict between the generalrequirements sheet and the data sheet,then the latter shall overrule.
