Industrial valves — Part-turn actuator attachments
1 Scope
This document 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.
This document 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 beyond the scope of this document.

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
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 can be electrical, pneumatic, hydraulic,
manual, etc., or a combination of these. Movement is limited by travel, torque (3.5) or thrust or combination of both.
3.2
multi-turn actuator
actuator (3.1) which transmits torque (3.5) to the valve for at least one revolution and may be capable of
withstanding thrust
Note 1 to entry: An actuator can be a combination of a multi-turn actuator and multi-turn gearbox (3.4).
3.3
part-turn actuator
actuator (3.1) which transmits torque (3.5) 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 can be a combination of a multi-turn actuator (3.2) and part-turn gearbox (3.4).
3.4
gearbox
mechanism designed to reduce the torque (3.5) required to operate a valve
3.5
torque
turning moment transmitted through the mounting flanges and connection components
Note 1 to entry: Torque is expressed in newton-metres (N·m).
4 Maximum flange torques
The flange torque shall comply with the values listed in Table 1 which represent the maximum torques
which can be transmitted through the mounting flange.

F48 125 000
F60 250 000
F80 500 000
F100 1 000 000
The values specified in Table 1 have been defined on the basis of bolts in tension only 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 values. See Annex A for more details on the calculation method.
The selection of flange types for a particular application should take into account the additional torques that
may be generated because of inertia or other factors.
5 Flange dimensions
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 of studs, screws or through bolting.
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 d . A spigot on the part-turn
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 h
e 3
shall be at least 1 × d .
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 and is a
1 3
minimum. The flange shape of both valve and actuator outside these areas of landing is left to the discretion
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 may be used, with no dimensional changes but with potential variation of the transmittable torque.
Above flange type F100 alternative dimensions and torque ratings may be used on agreement between
manufacturer/supplier and purchaser.

EXAMPLE
ISO 5211 – F05 Y – V – 18 identifies a part-turn valve actuator attachment according to this document, with
F05 flange type, spigot and single-key drive with 18 mm diameter.
NOTE The designation is not a marking requirement.
7 Dimensions and torques
7.1 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
of the component materials. In some cases, it can be necessary to use materials with superior mechanical
properties and/or to reduce the output torque of the actuator.
7.2 Drive by key(s)
Dimensions of the drive components for key drive shall meet the requirements of Figure 4 and Table 4.
The values of d , h and l in Table 4 are based on single-key design up to 98 mm shaft diameter.
7 4 5
Where more than one key is required to transmit the torque, the dimensions in Table 4 shall still apply.
The key dimensions shall conform with those given in Annex B or any national standard.
The keyway(s) in the driving component shall correspond to the position of the key(s) supplied on the driven
component as specified in 8.1, Figures 11, 12 or 13.
The key(s) shall be secured in position by suitable means.

The flange on the valve shall have a recess corresponding to the diameter d . A spigot on the part-turn
actuator is optional.
The minimum values for dimension h shown in Table 20 apply to flanges having material of proof stress
Re ≥ 200 MPa. The minimum values for dimension h2 applied to flanges having materials of proof stress
R ≤ 200 MPa shall be agreed between manufacturer and purchaser. The minimum values for dimension
e
h3 shall be at least 1 × d4.
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 and is a
1 3
minimum. The flange shape of both valve and actuator outside these areas of landing is left to the
discretion 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 canmay be used, with no dimensional changes but with potential variation of the transmittable
torque.
Above flange type F100 alternative dimensions and torque ratings may be used on agreement between
manufacturer/supplier and purchaser.

PROJET FINAL Norme internationale ISO/FDIS 5211:2025(fr)
Robinetterie industrielle — Raccordement des actionneurs à
fraction de tour
1 Domaine d'application
Le présent document spécifie les exigences pour le raccordement des actionneurs à fraction de tour, avec ou
sans réducteur, aux appareils de robinetterie industrielle.
Le raccordement des actionneurs à fraction de tour aux robinets de régulation conformément aux
spécifications du présent document est soumis à accord entre le fournisseur et l'acheteur.
Le présent document spécifie:
— les dimensions des brides nécessaires pour le raccordement des actionneurs à fraction de tour aux
appareils de robinetterie industrielle [voir Figures 1 a) et 1 c)] ou aux supports intermédiaires [voir
Figures 1 b) et 1 d)];
— les dimensions des éléments d'entraînement des actionneurs à fraction de tour nécessaires pour les
raccorder aux éléments entraînés;
— les valeurs de référence des couples pour les interfaces et les éléments d'accouplement dont les dimensions
sont spécifiées dans le présent document.
Le raccordement du support intermédiaire à l'appareil de robinetterie est en dehors du domaine d'application
du présent document.

3.1
actionneur
dispositif d'entraînement prévu pour être raccordé à un appareil de robinetterie industrielle d'usage général
afin d’assurer le fonctionnement de l’appareil de robinetterie
Note 1 à l'article: Le dispositif est conçu pour fonctionner avec une énergie motrice qui peut être d'origine électrique,
pneumatique, hydraulique, manuelle, etc., ou une combinaison de celles-ci. Le mouvement est limité par la course, le
couple (3.5) ou la poussée ou la combinaison des deux.
3.2
actionneur multitour
actionneur (3.1) qui transmet le couple (3.5) à l'appareil de robinetterie, pendant au moins une rotation d’un
tour, et qui peut être capable de supporter la poussée
Note 1 à l'article: Un actionneur peut être une combinaison d'un actionneur multitours et d'un réducteur (3.4)
multitours.
3.3
actionneur à fraction de tour
actionneur (3.1) qui transmet le couple (3.5) à l'appareil de robinetterie pendant une rotation d’un tour ou
moins et n'a pas à supporter d'effort axial
Note 1 à l'article: Un actionneur à fraction de tour peut être une combinaison d'un actionneur multitours (3.2) et d'un
réducteur (3.4) à fraction de tour.
3.4
réducteur
mécanisme conçu pour réduire le couple (3.5) requis pour faire fonctionner un appareil de robinetterie

Les valeurs spécifiées dans le Tableau 1 ont été définies sur la base de boulons sollicités seulement en traction
à une contrainte de 290 MPa et un coefficient de frottement de 0,2 entre l'interface d'accouplement. Toutes
les variations de ces paramètres définis entraînent des variations des valeurs de couples transmissibles.
Voir l’Annexe A pour de plus amples informations sur la méthode de calcul.
Pour le choix des types de bride pour une application particulière, il convient de prendre en compte les
couples additionnels qui peuvent être engendrés par l'inertie ou d'autres facteurs.
5 Dimensions des brides
Les brides pour le raccordement des actionneurs à fraction de tour doivent être conformes aux dimensions
indiquées à la Figure 2 et données dans le Tableau 2. La méthode de raccordement doit être effectuée au
moyen de goujons, vis ou par boulonnage.
Les trous pour les goujons, vis ou boulons doivent être équidistants et positionnés hors-axe (voir la Figure 3
et le Tableau 3), et conformes aux exigences de l'ISO 273.
La bride sur l'appareil de robinetterie doit avoir un lamage correspondant au diamètre d . Un bossage de
centrage sur l'actionneur à fraction de tour est optionnel.
Les valeurs minimales de dimension h données au Tableau 2 s'appliquent aux brides dont les matériaux ont
une limite conventionnelle d'élasticité R ≥ 200 MPa. Les valeurs minimales de dimension h appliquées aux
e 2
brides dont les matériaux ont une limite conventionnelle d'élasticité R ≤ 200 MPa doivent faire l'objet d'un
e
accord entre le fabricant et l'acheteur. Les valeurs minimales de dimension h doivent être d'au moins 1 × d .
3 4
La dimension d a été calculée pour fournir une surface d'assise suffisante aux écrous et têtes de boulons,
lorsque cela s'applique. Cette surface d'assise est définie comme un rayon de dimension minimale
(d − d ) / 2 ayant son origine au centre du trou de boulon. La forme de la bride de l'appareil de robinetterie
1 3
et de l'actionneur en dehors de ces surfaces d'assise sont laissées au choix du fabricant.
Les dimensions et le matériau de boulonnerie sont basés sur des boulons sollicités en traction à une
contrainte maximale de 290 MPa. Sur un accord entre le fabricant/fournisseur et l'acheteur, le matériau de
boulonnerie ayant une résistance à la traction différente peut être utilisé, sans changement de dimensions
mais avec une variation potentielle du couple transmissible.
Au-delà du type de bride F100, d'autres relations dimensions et couple peuvent être utilisés sur accord entre
le fabricant et l'acheteur.

EXEMPLE
ISO 5211 – F05 Y – V – 18 identifie un raccordement d'un actionneur à fraction de tour d’appareil de
robinetterie conformément au présent document, avec une bride de type F05, un bossage de centrage et un
entraînement avec une clavette unique avec un diamètre de 18 mm.
NOTE La désignation n'est pas une exigence de marquage.
7 Dimensions et couples
7.1 Généralités
Afin de s'assurer qu'aucune interférence ne puisse se produire entre l'élément entraînant et l'élément
entraîné, la longueur de l'élément entraîné au-dessus de l'interface doit être limitée, de façon qu'il y ait un jeu
entre les deux pièces.
Il convient de considérer la profondeur d'engagement des éléments entraînés de l'appareil de robinetterie
dans l'élément d'entraînement de l'actionneur et l'aire de surface de contact entre les faces de l'élément
d'entraînement de l'actionneur et les faces de l'élément entraîné de l'appareil de robinetterie, pour s'assurer
que les contraintes dues au contact n'excèdent pas la capacité des matériaux des éléments. Dans certains cas
il peut être nécessaire d'utiliser des matériaux avec des propriétés mécaniques supérieures et/ou de réduire
le couple de sortie de l'actionneur.
7.2 Entraînement par clavette(s)
Les dimensions des éléments d'entraînement par clavette doivent être conformes aux exigences de la
Figure 4 et du Tableau 4.
Les valeurs de d , h et l du Tableau 4 sont basées sur une conception à clavette unique jusqu'à 98 mm de
7 4 5
diamètre d'arbre.
Lorsque plus d'une clavette est nécessaire pour transmettre le couple, les dimensions du Tableau 4 doivent
toujours s’appliquer.
Les dimensions de clavette doivent être conformes à celles données en Annexe B ou n'importe quelle norme
nationale.
Le(s) passage(s) de(s) clavette(s) dans l'élément d’entraînement doit(doivent) correspondre à la position de
la(des) clavette(s) fournie(s) sur l'élément entraîné tel(s) que spécifié(s) en 8.1, Figures 11, 12 ou 13.
La(les) clavette(s) doit(doivent) être maintenue(s) en place par des moyens appropriés.
