Industrial-process control valves -- Part 5: Marking

specifies mandatory and supplementary markings of control valves. Some mandatory markings may be inappropriate for some valves of special design, and some supplementary markings may be appropriate only to specific types of control valves. It is recommended that the marking of all valves conform to this standard whenever possible unless otherwise agreed between the manufacturer and purchaser.

Vannes de régulation des processus industriels -- Partie 5: Marquage

spécifie les marquages obligatoires et supplémentaires des vannes de régulation. Certains marquages obligatoires peuvent ne pas convenir à des vannes de certains types ou de conception spéciale, et quelques marquages supplémentaires peuvent seulement convenir à des types spécifiques de vannes de régulation. Il est recommandé, dans la mesure du possible, que les marquages pour toutes les vannes soient conformes à la présente norme à moins d'un accord entre le fabricant et l'acheteur.

Overview

EN 60534-5:2004 (IEC 60534-5:2004) defines the marking requirements for industrial-process control valves. The standard specifies which markings are mandatory and which are supplementary, how and where markings should be applied (integral on the body, on a marking plate or on an identification plate), and guidance when space or special designs limit marking. EN 60534-5:2004 supports traceability, safe installation, correct valve selection and ongoing maintenance by standardizing valve identification and labelling.

Key topics and requirements

• Mandatory vs supplementary markings: Mandatory markings are normally integral or on a marking plate and must be permanent; supplementary markings are typically on an identification plate.
• Mandatory items (examples):
  • Nominal size (DN, NPS)
  • Pressure rating (PN, Class)
  • Material of body shell
  • Manufacturer’s name or trade mark
  • Serial number or permanent identification
• Supplementary items (examples):
  • Manufacturer’s type/model
  • Material of trim or lining
  • Rated flow coefficient (Kv, Cv)
  • Rated travel, inherent flow characteristic, tag number, actuator bench setting
• Location rules:
  • Body markings must be permanent and integral or on a securely fixed marking plate.
  • Flange/end-connection specifics (e.g., ring joint number) must be marked on flanges if applicable.
  • Identification plates may be removable when user-modifiable characteristics are recorded.
• Special cases and limitations:
  • Valves smaller than DN 50 (NPS 2) may omit some body markings; these should then appear on the identification plate.
  • Special-service valves (oxygen, nuclear, fugitive emissions) should carry additional agreed markings.
• Symbol and material notation: Use ISO references where possible; recognized abbreviations (e.g., CF8M / 316) are acceptable.

Applications and users

EN 60534-5:2004 is essential for:

• Valve manufacturers (ensuring compliant, traceable products)
• Plant engineers and procurement professionals (specifying and verifying valve identity and ratings)
• Piping and instrumentation (P&ID) engineers and maintenance teams (correct installation, replacement and repair)
• Inspectors and QA/quality control (verifying conformity and safety) Practical uses include procurement specifications, asset tagging, maintenance records, and ensuring compatibility with piping and pressure systems.

Related standards

• EN 19 - Marking of metallic valves
• IEC 60534-1 - Control valve terminology and general considerations
• ISO 5209 - General purpose industrial valves - Marking
• EN 1092 / ISO 7005 - Flange identification and PN/class definitions
• EN 1333 - Definition and selection of PN

Using EN 60534-5:2004 for valve marking improves safety, traceability and interoperability across industrial installations.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.
