Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 153, Valves, in collaboration with the
European Committee for Standardization (CEN) Technical Committee CEN/TC 69, Industrial valves, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

Industrial valves — Part-turn actuator attachments
AMENDMENT 1
7.2, fourth paragraph
Replace the fourth paragraph by the following:
The key dimensions shall comply with those given in Annex B.

Annex B
Add the following new normative Annex B.
ISO 5211:2017/DAM 1:2022(E)
Annex B
(normative)
Dimensions of keys and keyways
B.1 Basis for keys and keyways dimensioning
With ISO R773: 1969 being withdrawn, there is currently no international standard defining keys and
keyways available. Since for driven by key (see 7.2), keys and keyways are the means to transfer torque
from the actuator to the valve, information on design and dimensions is given in Annex B.
B.2 Key and keyway forms
Forms for key and keyway shall fulfill the requirements given in Figure B.1 to Figure B.3.
Keys and keyways according to low patterns are not described in this Annex.
Bolts for retaining of keys, slants for disassembly of keys and holes for spiral pins are common with
larger key sizes, but are not described in this Annex.
a) Form A round-ended b) Form B square-ended c) Form AB combination of A and B
d) Cross section through key and keyway connection, definition of the depths t and t

B.3 Dimensions and tolerances (cross section and design details)
The dimensions of the keys and keyways, as well as their acceptable deviations, shall be in accordance
with those given in Tables B.1 and B.2.
