This is Part 7 of GB/T 17213.
This part was drafted in accordance with the rules given in the GB/T 1.1-2009.
This part replaces GB/T 17213.7-1998 Industrial-process Control Valves — Part 7: Control Valve Data Sheet. The following technical deviations have been made with respect to GB/T 17213.7-1998 (the previous edition):
— deletion of the clauses of Introduction and Purpose of Edition 1998 (see Clauses 1 and 2 of Edition 1998);
— modification of normative references and addition of reference GB/T 4208-2008 Degrees of Protection Provided by Enclosure (IP Code) (see Clause 2);
— modification of the suspension section in Clause 6 of Edition 1998 and changed to 4.1 (see 4.1; Clause 6 of Edition 1998);
— modification of the three different levels of control valve selection as “preliminary valve specification”, “inquiry valve specification” and “order valve specification” (see 4.2, 4.3, 4.4; Edition 1998, 6.1, 6.2, 6.3);
— deletion of the inherent flow characteristics and adjustable ratios that may need to be included in the basic requirements list [see Edition 1998, 7.3 d)];
— addition of the final inspection requirements that may need to be included in the basic requirements list [see 5.3k)];
— deletion of the suspension section of Clause 8 of the original standard (see Clause 8 of the Edition 1998);
— updating of the description of the instructions for numbered lines (see 6.3; Edition 1998, 8.3);
— modification of the contents of control valve data sheet (see Figure 1; Edition 1998, Figure 1).
This part is identical with International Standard IEC 60534-7:2010 Industrial-process Control Valves — Part 7: Control Valve Data Sheet by means of translation.
The documents, referenced in this part, which correspond to those in the international standard, are as below:
— GB/T 17213 (all parts) Industrial-process Control Valves [IEC 60534 (all parts)]
For the purpose of this part, the following editorial changes have been made on the base of ISO 60534-7:2010:
— modification of the erroneous unit of liquid and vapor density in 6.3, item 20, change "kg3/m" to "kg/m3".
— according to the legal unit of measurement, the pressure unit “bar” of items 10, 62 and 63 in Figure 1 is modified to “MPa, kPa”.
This part was proposed by the China Machinery Industry Federation.
This standard is under the jurisdiction of the National Technical Committee 124 on Industrial Process Measurement Control and Automation of Standardization Administration of China (SAC/TC 124).
The previous editions of this part are as follows:

Industrial-process Control Valves — Part 7: Control Valve Data Sheet
1 Scope
This part of the GB/T 17213 series provides a list of requirements that are normally necessary for the procurement of the majority of control valves for process systems. No attempt is made to include all possible requirements for any conceivable process.
The list in this part is arranged in a format designed 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 this part, in order to ensure that the abbreviated terms are fully understood and that consistent data entries are always made.

3 Terms and Definitions
For the purposes of this document, the terms and definitions given in the other parts of IEC 60534 apply.
4 Application
4.1 General
The control valve data sheet (Figure 1) below may be used for three different levels of control valve selection.
4.2 Preliminary valve specification
For a preliminary inquiry and/or quotation, buyer and vendor may agree on a minimum level of information. 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.
4.3 Inquiry valve specification
In inquiry stage, some of the process data and also some of the general requirements will not be fully known and specified. This may not allow the application of the calculation methods given in GB/T 17213.2 and GB/T 17213.17. Preliminary valve sizing methods may be used at this stage. Since the main focus of the inquiry specification is to provide all data required to work out a comparable technical and commercial quote, in most cases there is a need to mark additional lines beyond those in 6.1. Also on the inquiry specification, the lines in column 1 shall be marked by a dot, triangle or other symbol by the buyer and manufacturer.
4.4 Order 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 sheet becomes a kind of passport, which allows an exact identification and can be used for many purposes.
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 means for the user to specify general or special requirements that are applicable to a valve or group of valves. Examples are national and international standards, user company standards and special project requirements. These general or special requirements shall be listed in the table of contents section 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 general requirements sheet(s) with the data sheets. If there is a conflict between the general requirements sheet and the data sheet, then the latter shall overrule.
Note: For those countries that use A4 paper (21 cm × 29.7 cm) and where linefeed is limited to 1/6 inch, the general requirements sheets can be shortened by deleting the appropriate length from the middle portion of the for ms. The data sheet c an be shortened by deleting the “Remarks” section. The use of computers permits an adjustable linefeed which allows the forms to be printed without the deletion of any lines.
5.2 Alternate location for data sheet items
Any item on the data sheet (Figure 1) which cannot be adequately described in the available space shall be covered on the general requirements sheet.
5.3 Items to be considered for inclusion in general requirements
Items not included on the data sheet may also be covered on the general requirements sheet. The following is a partial list of areas that may need to be considered and to be stated on the general requirements sheet:
a) terminology (see GB/T 17213.1);
b) codes, standards and regulations;
c) valve sizing (see GB/T 17213.2 and GB/T 17213.17);
d) noise (see GB/T 17213.15, respectively GB/T 17213.16);
e) inspection and routine testing (see GB/T 17213.4);
f) non-destructive examination;
g) marking (see GB/T 17213.5);
h) documentation;
i) material requirements;
j) face-to-face dimensions (see GB/T 17213.3, GB/T 17213.11 and GB/T 17213.12)
k) final inspection requirements (see GB/T 17213.4)
l) environmental considerations;
m) packaging;
n) accessories;
o) quality assurance requirements.
