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).

Note 1 to entry: This is the torque used to design the mechanically loaded parts of the actuator.

[SOURCE: ISO 12490:2011, 4.23, modified — The word "thrust" was added to the term, the phrase "or a

combination of both" has been added to the definition.]

from the fully open position to the fully closed position or vice-versa.

B Inching/positioning The electric actuator is required to occasionally drive the valve to any

position (fully open, intermediate and fully closed).

position between fully open and fully closed.

D Continuous modulating The electric actuator is required to continuously drive the valve to

any position between fully open and fully closed.
4.4 Action on loss of external electric power

One cycle consists of nominal 90° angular travel in both directions (i.e. 90° to open and 90° to close). The actuator

is able to transmit 100 % of the rated torque for at least 4,5° at each end of travel or for at least 9° at either opened or

closed position in both directions. The average load cannot be below 30 % of the rated torque for the remaining travel

(see Annex C). For angular travel other than 90°, the endurance is agreed between the purchaser and the manufacturer or

supplier. During testing a deviation of +20 % and −5 % in load is accepted.

One start consists of a movement of at least 1 % in either direction, with a load of at least 30 % of the rated torque.

T.B.A. means to be agreed between manufacturer/supplier and purchaser.
