Industrial valves - Part-turn actuator attachments
ISO 5211:2017 specifies requirements for the attachment of part-turn actuators, with or without gearboxes, to industrial valves.The attachment of part-turn actuators to control valves in accordance with the requirements of this document is subject to an agreement between the supplier and the purchaser.ISO 5211:2017 specifies:- flange dimensions necessary for the attachment of part-turn actuators to industrial valves [see Figures 1 a) and 1 c)] or to intermediate supports [see Figures 1 b) and 1 d)];- driving component dimensions of part-turn actuators necessary to attach them to the driven components;- reference values for torques for interfaces and for couplings having the dimensions specified in this document.The attachment of the intermediate support to the valve is out of the scope of this document.

La présente norme internationale spécifie les prescriptions pour le raccordement des actionneurs à fraction de tour avec ou sans démultiplicateur aux appareils de robinetterie industrielle. Le raccordement des actionneurs à fraction de tour aux robinets de régulation est conforme aux prescriptions de cette norme seulement en cas d'accord entre le fournisseur et l'acheteur. Cette norme spécifie : - les dimensions des embases nécessaires pour le raccordement des actionneurs à fraction de tour aux appareils de robinetterie industrielle ou aux supports intermédiaires ; - les dimensions des éléments d'entraînement des actionneurs à fraction de tour nécessaires pour les accoupler aux éléments entraînés ; - les valeurs de référence des couples pour les interfaces et les éléments d'accouplement dont les dimensions sont spécifiées dans la présente norme. Le raccordement du support intermédiaire à l'appareil de robinetterie ne fait pas l'objet de cette norme. NOTE 1 Dans cette norme internationale, il est possible de comprendre «appareil de robinetterie» comme étant également l'association d'un «appareil de robinetterie» et d'un «support intermédiaire». NOTE 2 Quand l'actionneur à fraction de tour est une combinaison d'un actionneur multitours et d'un démultiplicateur, il convient que le raccordement de l'actionneur multitours au démultiplicateur soit conforme à l'ISO 5210.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
With Requirements, quickly access the main part of the normative text!

At a glance, you will be able to identify the additions, deletions or modifications to a text, table, figure and formula.
