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.
International Standard IEC 60534-3-1 has been prepared by subcommittee 65B: Measurement
and control devices, of IEC technical committee 65: Industrial-process measurement, control
and automation.
This second edition cancels and replaces the first edition published in 2000. This edition
constitutes a technical revision.
The main changes with respect to the previous edition are listed below:
• this document has been extended to cover face-to-face dimensions and centre-to-face
dimensions for control valves PN 160 and PN 250 (Class 900 and 1 500);

• Table 5 of adjustment value “X” for end-to-end dimensions of straight pattern valves with
ring joint ends has been added;
• ANSI/ISA references have been added in Tables 1 to 4;
• ANSI/ISA references have been added in the bibliography.

Part 3-1: Dimensions – Face-to-face dimensions for flanged,
two-way, globe-type, straight pattern and centre-to-face
dimensions for flanged, two-way, globe-type,
angle pattern control valves
1 Scope
This part of IEC 60534 specifies face-to-face (FTF) and centre-to-face (CTF) dimensions for
given nominal sizes and pressure ratings of flanged, two-way, globe-type, straight pattern and
angle pattern control valves. The nominal sizes included are DN 15 to DN 400 for straight
pattern control valves and DN 15 to DN 400 for angle pattern control valves.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their
content constitutes requirements of this document. For dated references, only the edition
cited applies. For undated references, the latest edition of the referenced document (including
any amendments) applies.
IEC 60534-1, Industrial-process control valves – Part 1: Control valve terminology and
general considerations
3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60534-1 and the
following apply.
ISO and IEC maintain terminological databases for use in standardization at the following
addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at http://www.iso.org/obp
3.1
straight pattern valve
valve where the outlet end connection is on the opposite side of the valve and in line with the
inlet end connection
3.2
angle pattern valve
valve where the inlet and the outlet end connections are arranged at a right angle with the
centerlines matching each other
3.3
face-to-face dimension (FTF)
distance between the faces of the connecting end flanges upon
which the gaskets are compressed, that is, the contact surfaces (see Figure 1)
3.4
centre-to-face dimension (CTF)
distance between the plane located at the face of either end
connection and perpendicular to its axis and the axis of the other end connection
(see Figure 1)
– 6 – IEC 60534-3-1:2019 © IEC 2019
3.5
end-to-end dimension (ETE)
distance between the extreme ends of the valve for those flanged
valves where the gasket contact surfaces are not located at the extreme ends of the valve
(see Figures 2 and 3)
3.6
centre-to-end dimension (CTE)
distance between the plane located at the extreme end of either
end connection and perpendicular to its axis and the axis of the other end connection for
those flanged valves where the gasket contact surfaces are not located at the extreme ends
of the valve (see Figures 2 and 3)
4 Nominal sizes and pressure ratings
4.1 Nominal sizes
Nominal sizes shall be as shown in Table 1 to Table 4.
4.2 Pressure ratings
Pressure ratings shall be grouped by Class and nominal pressure (PN) as shown in
Table 1 to Table 4.
Figure 1 – Face-to-face and centre-to-face dimensions
Figure 2 – End-to-end and centre-to-end dimensions
Figure 3 – Details of RTJ flanges
5 Face-to-face and centre-to-face dimensions
FTF and CTF dimensions shall be taken from Table 1 to Table 4. These tables shall be used
only in conjunction with the range of nominal sizes and groups of pressure ratings given in the
tables.
Control valve FTF and CTF dimensions taken from a given pressure rating group shall be the
same; however, control valves may differ in other respects.
NOTE Pressure ratings have been grouped as shown in the tables in order to restrict the number of FTF and CTF
dimensions.
6 Tolerances
Tolerances on FTF and CTF dimensions shall be as shown in Table 1 to Table 4.
7 Flange facings
This document only provides FTF and CTF dimensions for control valves with plain-face or
raised-face flanges. The FTF and CTF dimensions include the raised face, if provided, as
specified in the appropriate flange standard.
For end-to-end dimensions of straight pattern valves with ring joint ends (Figure 2b),
dimension „X“ as given in Table 5 shall be added to the face-to-face dimension given in
Table 1 and Table 2. For centre-to-end dimension of angle pattern valves with ring joint ends
half of dimension „X“ shall be applied to the centre-to-face dimension given in Table 3 and
Table 4.
Dimension “X” as given in Table 5 is taken from the metric values given in ASME B16.10-
2009.
Control valves with flanges having other special facings such as male and female flange
facing or tongue-and-groove are not covered by this part of IEC 60534.
