FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
The writing of control valve specifications is an extremely important segment of the complete
design, purchase and manufacturing of any process control system.
If the wrong control valve is specified, due to either incomplete or erroneous specification, the
replacement of that valve becomes costly to both the user and the control valve manufacturer
and often results in undue project delay. Therefore, many of the important control valve users
and contractors have developed their own standard data sheets to eliminate as much
misunderstanding as possible regarding the valve specifications.
To avoid confusion between valve manufacturers, users and contractors, standardisation of
the datasheet is required.
The purpose of a standard control valve data sheet is to promote uniformity, both in content
and form. General use of this form by contractors, users and manufacturers offers many
advantages. For example:
· assisting in preparation of a complete specification by listing and providing space for
all principal descriptive options;
· promoting uniform terminology;
· facilitates quoting, purchasing, receiving, accounting and ordering procedures by
uniform display of information;
· providing a useful permanent record and information for checking;
· improving efficiency from initial concept to the final installation.

Part 7: Control valve data sheet

1 Scope
This part of the IEC 60534 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 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 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 IEC 60534 series
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 IEC calculation
methods given in IEC 60534-2-1 and IEC 60534-2-5. 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.

– 8 – 60534-7 Ó IEC:2010
NOTE For those countries that use 8,5 ´ 11 inch paper 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 forms. The
data sheet can 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 IEC 60534-1);
b) codes, standards and regulations;
c) valve sizing (see IEC 60534-2-1 and 60534-2-5);
d) noise (see IEC 60534-8-3, respectively IEC 60534-8-4);
e) inspection and routine testing (see IEC 60534-4);
f) non-destructive examination;
g) marking (see IEC 60534-5);
h) documentation;
i) material requirements;
j) face-to-face dimensions (see IEC 60534-3-1, IEC 60534-3-2 and IEC 60534-3-3)
k) final inspection requirements (see IEC 60534-4)
l) environmental considerations;
m) packaging;
n) accessories;
o) quality assurance requirements.
6 Preparation of data sheet (see Figure 1)
6.1 Identification blocks
The identification blocks at the top and bottom of this form are designed to permit the user or
contractor to add company name (upper left-hand corner), plant location, project number, tag
number, piping and instrumentation (P and I) drawing number, and other specific project data.
6.2 Explanation of numbered columns
The meaning of the numbered columns (1-5) under the heading is as follows:
(1) marking of lines for a preliminary valve specification or inquiry valve specification as
agreed between buyer and vendor (see 4.1 and 4.2);
(2) numbering of individual lines for identification purposes;
(3) marking of revisions (e.g. capital letters);
(4) main categories for which information is required;

NOTE Springless actuators (piston type) usually need a double acting positioner providing two
pneumatic output pressures acting on both sides of the piston.
75 Required positioner characteristic to produce requested control valve
characteristic. Digital positioners often allow a free programmable positioner
characteristic.
NOTE Normally the positioner characteristic is linear, but in some applications a special positioner
