Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work o f 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 o f
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
di fferent types o f ISO documents should be noted. This document was dra fted 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 o f the elements o f this document may be the subject o f
patent rights. ISO shall not be held responsible for identi fying any or all such patent rights. Details o f
any patent rights identified during the development o f the document will be in the Introduction and/or

NOTE 2 When a combination of a multi-turn actuator and separate part-turn gearbox is coupled to form a
part-turn actuator, the multi-turn attachment to the gearbox is in accordance with ISO 5210:2017, Figures 1 c)

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 o f these. Movement is limited by travel, torque and/or thrust.
3.2
multi-turn actuator
actuator which transmits torque to the valve for at least one revolution and may be capable o f
withstanding thrust
Note 1 to entry: An actuator may be a combination o f a multi-turn actuator and multi-turn gearbox.
3.3
part-turn actuator
actuator which transmits torque to the valve for a rotation of one revolution or less and does not have
to withstand axial thrust
Note 1 to entry: A part-turn actuator may be a combination o f a multi-turn actuator and part-turn gearbox.

The values specified in Table 1 have been defined on the basis o f bolts in tension only at a stress o f
290 MPa and a coe fficient o f friction o f 0,2 between the mounting inter face. All variations in these
defined parameters lead to variations o f the transmittable torque values. See Annex A for more details
on the calculation method.
The selection o f flange types for a particular application should take into account the additional torques
that may be generated because o f inertia or other factors.

Flanges for part-turn actuator attachments shall comply with the dimensions shown in Figure 2 and
given in Table 2 . The method of attachment shall be by means o f studs, screws or through bolting. When
through bolting is used, the diameter of the clearance holes shall permit the use of bolts of a size given
by the corresponding dimension d4 in Table 2.
Holes for the studs, screws or bolts shall be equi-spaced and positioned off-centre (see Figure 3 and
Table 3) and shall conform to the requirements of ISO 273.
The flange on the valve shall have a recess corresponding to the diameter d2 . A spigot on the part-turn
actuator is optional.
The minimum values for dimension h2 shown in Table 2 apply to flanges having material of proof stress
Re ≥ 200 MPa. The minimum values for dimension h 2 applied to flanges having materials o f proo f stress
Re ≤ 200 MPa shall be agreed between manu facturer and purchaser. The minimum values for dimension
h 3 shall be at least 1 × d4 .
Dimension
d1 has been based on providing su fficient landing for the nuts and bolt heads where
applicable. Such landing is defined as a radius from the bolt hole centre with the dimension (d1 − d3 ) / 2,
and is a minimum. The flange shape o f both valve and actuator outside these areas o f landing is left to
the option of the manufacturer.
The dimensions and bolting material are based on bolts in tension at a maximum stress o f 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.
Above flange type F60 alternative dimensions and/or torque ratings may be used on agreement
between manufacturer/supplier and purchaser.

General
To ensure that no interference can occur between the driving component and the driven component,
the length of the driven component above the interface shall be limited so that there is a clearance
between both parts.
The depth of engagement of the valve driven component into the actuator drive component and the
surface area of contact between the faces of the actuator drive component and the faces of the valve
driven component should be considered to ensure that the stresses caused by contact do not exceed
the capability o f the component materials. In some cases, it may be necessary to use materials with
superior mechanical properties and/or to reduce the output torque of the actuator.
