Industrial valves — Mounting kits for part-turn valve actuator attachment

This document provides requirements for metallic mounting kits for part-turn valves and actuator attachments. It includes all components transmitting torques from actuators to valves with a maximum flange torque up to 16 000 Nm (up to F30 flange type). It applies to mounting kits for part-turn valves and actuators with integral attachment flanges and drive components as described in ISO 5211, when direct mounting of the actuator on valve is not practical. Stacking of mounting kits/intermediate supports is not within the scope of this document. This document specifies methods for design and environmental corrosion protection. When a reference is made to this document, all the requirements apply, unless otherwise agreed between the purchaser and the manufacturer/supplier, prior to order. In this document, the term "valve" covers valve or shaft extension top-flange, and the term “actuator” covers part-turn actuator or combination of multi-turn actuator and gearbox. Control valves are excluded from this document.

Robinetterie industrielle — Kits de montage de raccordement des actionneurs à fraction de tour

Le présent document fournit des exigences pour les kits de montage métalliques de raccordement des appareils de robinetterie et des actionneurs à fraction de tour. Il inclut tous les éléments qui transmettent des couples des actionneurs aux appareils de robinetterie, avec un couple maximal de la bride jusqu’à 16 000 Nm (jusqu’au type de bride F30). Il s'applique aux kits de montage de raccordement des appareils de robinetterie et actionneurs à fraction de tour avec brides de raccordement intégrées et éléments d'entraînement tels que décrits dans l'ISO 5211 (voir Figure 1), lorsque le montage direct de l'actionneur sur l'appareil de robinetterie n'est pas pratique. La Figure 1 illustre les deux types différents de kits de montage dans le domaine d’application du présent document.

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 cautioned that
this may not represent the latest information, which may be obtained from the patent database available at

Industrial valves — Mounting kits for part-turn valve actuator
attachment
1 Scope
This document provides requirements for metallic mounting kits for part-turn valves and actuator
attachments.
It includes all components transmitting torques from actuators to valves with a maximum flange torque up
to 16 000 Nm (up to F30 flange type).
It applies to mounting kits for part-turn valves and actuators with integral attachment flanges and drive
components as described in ISO 5211 (see Figure 1), when direct mounting of the actuator on valve is not
practical. Figure 1 illustrates the two different types of mounting kits in the scope of this document.
a) Direct interface with mounting kit b) Direct interface with mounting kit (when com-
bination of a multi-turn actuator and a gearbox)
Key
1 part-turn actuator 5 gearbox
2 interface (see ISO 5211) 6 interface (see ISO 5210)
3 valve 7 multi-turn actuator
4 mounting kit

Stacking of mounting kits/intermediate supports is not within the scope of this document.
This document specifies methods for design and environmental corrosion protection.
When a reference is made to this document, all the requirements apply, unless otherwise agreed between
the purchaser and the manufacturer/supplier, prior to order.
In this document, the term "valve" covers valve or shaft extension top-flange, and the term “actuator” covers
part-turn actuator or combination of multi-turn actuator and gearbox.
Control valves are excluded from this document.
