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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are

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 is, in general, considered in conjunction with the specific requirements which may be
agreed between the parties concerned.
NOTE 1 In this document, the term “valve” can 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).

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” can 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.
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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
3.1
actuator
any device designed for attachment to a general-purpose industrial valve in order to provide for the
operation of the valve
Note 1 to entry: The device is designed to operate using motive energy which may be electrical, pneumatic,
hydraulic, manual, etc., or a combination of these. Movement is limited by travel, torque (3.4) and/or thrust (3.5).
3.2
multi-turn actuator
actuator (3.1) which transmits torque (3.4) to the valve for at least one revolution and may be capable of
withstanding thrust (3.5)
Note 1 to entry: An actuator may be a combination of a multi-turn actuator and multi-turn gearbox.
ISO 5210:2023(E)
3.3
linear actuator
actuator (3.1) which transmits thrust (3.5) to the valve for a defined linear stroke
Note 1 to entry: An actuator may be a combination of a multi-turn actuator (3.2) and linear gearbox.
3.4
torque
turning moment transmitted through the mounting flanges and couplings
Note 1 to entry: Torque is expressed in newton-metres.
3.5
thrust
axial force transmitted through the mounting flanges and couplings
Note 1 to entry: Thrust is expressed in kilonewtons.
4 Maximum torques and thrusts
The torque and thrust shall comply with the values listed in Table 1 which represent the maximum
torques and thrusts which can be transmitted simultaneously through the mounting flanges and
couplings. They are based upon specified criteria.
Table 1 — Maximum torque and thrust values
Torque Thrust
Flange type
[Nm] [kN]
F05 20 10
F07 40 20
F10 100 40
F12 250 70
F14 400 100
F16 700 150
F25 1 200 200
F30 2 500 325
F35 5 000 700
F40 10 000 1 100
F48 20 000 2 000
F60 40 000 4 000
The values specified in Table 1 have been defined on the basis of bolts in tension at a stress of 290 MPa
and a coefficient of friction of 0,2 between the mounting interface. All variations in these defined
parameters lead to variations of the transmittable torque and/or thrust values. See Annex A for an
explanation on the calculation method.
The selection of flange size for a particular application should take account of additional torques and/or
thrust that may be generated at the valve stem because of sizing, safety factors, inertia or other similar
factors. Specifically, the torque and thrust generated at the maximum output torque and/or thrust of
the selected actuator shall be calculated and considered in the selection of the flange along with the
ability of the valve and actuator to withstand such torque and thrust forces.
5 Flange dimensions
Flanges for actuator attachment shall comply with the dimensions shown in Figure 2 and given
in Table 2. The method of attachment shall be by means of studs or through bolting. When through
ISO 5210:2023(E)
bolting is used, the diameter of the clearance holes shall permit the use of bolts of a size given by the
corresponding dimension d in Table 2.
Holes for the studs/bolts shall be positioned off-centre (see Figure 3 and Table 3), shall be equi-spaced
and shall conform to the requirements of ISO 273.
The interface on the valve shall have a recess corresponding to the diameter d . A spigot on the actuator
is optional.
The minimum values for dimension h shown in Table 2 apply to flanges having material of proof stress
R ≥ 200 MPa. The minimum values for dimension h applied to flanges having materials of proof stress
e 2
R ≤ 200 MPa shall be agreed between manufacturer and purchaser. The minimum values for dimension
e
h shall be at least 1 × d .
3 4
Dimension d has been based on providing sufficient landing for the nuts and bolt heads where
applicable. Such landing is defined as a radius from the bolt hole centre with the dimension (d − d ) / 2,
1 3
and is a minimum. The flange shape of both valve and actuator outside these areas of landing is left to
the option of the manufacturer.
The dimensions and bolting material are based on bolts in tension at a maximum stress of 290 MPa. On
agreement, between the manufacturer/supplier and purchaser, bolting material with different tensile
strength can be used, with no dimensional changes but with potential variation of the transmittable
torque and thrust value.
