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.

This document was prepared by Technical Committee ISO/TC 153, Valves.
This second edition cancels and replaces the first edition (ISO 5210:1991), which has been technically
revised with the following changes:
a) extension of flange sizes;
b) introduction of groups C and D for assemblies capable of transmitting torque, in 7.4 and 7.5;
c) introduction of linear actuator in 7.6.

Introduction
The purpose of this document is to establish certain basic requirements for the attachment of multi-
turn actuators, in order to define the interface between actuator and valve.
This document has, in general, to be considered in conjunction with the specific requirements which
may be agreed between the parties concerned.
INTERNATIONAL STANDARD ISO 5210:2017(E)
Industrial valves — Multi-turn valve actuator attachments
1 Scope
This document specifies the requirements for the attachment of multi-turn actuators to valves.
Throughout this document, “actuator” may be understood as “actuator and/or gearbox” providing a
multi-turn and/or linear output.
It specifies:
— flange dimensions necessary for the attachment of actuators to industrial valves [see Figure 1 a)] or
to intermediate supports [see Figure 1 b)];
— those driving component dimensions of actuators which are necessary to attach them to the driven
components;
— reference values for torque and thrust for flanges having the dimensions specified in this document.
NOTE 1 In this document, the term “valve” may also be understood to include “valve with an intermediate
support” [see Figure 1 b)].
NOTE 2 When a combination of a multi-turn actuator and separate multi-turn/linear gearbox is coupled to
form an actuator, the multi-turn attachment to the gearbox is in accordance with this document [see Figures 1 c)
and 1 d)]. A combination of a multi-turn actuator with integral multi-turn/linear gearbox supplied as an actuator
is in accordance with Figures 1 a) and 1 b).
