Le détail technique qui dissocie l’approvisionnement en actionneurs de la sélection des actionneurs.

Dimensionnement du couple — Fourni avec chaque devis


Fiche technique des couples de la vanne, conditions de fonctionnement les plus défavorables (ΔP maximal avec une alimentation minimale), coefficient de sécurité appliqué (généralement de 1,25 à 1,5 fois) et couple de sortie de l’actionneur confirmé par écrit — tout cela doit être établi avant l’émission de votre bon de commande. Pas une fois que l’actionneur est arrivé et qu’il s’avère incapable de manœuvrer la vanne.

Calcul de batterie pour système de secours (ESD) — Standard pour les commandes incluant une batterie de secours

Pour les actionneurs électriques de sécurité (ESD) équipés d’une batterie de secours, nous calculons la capacité de batterie nécessaire pour assurer le nombre spécifié de manœuvres sur toute la course, à la température ambiante minimale. Les caractéristiques de la batterie sont confirmées lors de l’établissement du devis, avec indication de l’intervalle de remplacement recommandé.

Ensembles d’éléments finaux certifiés SIL — PFD au stade de l’offre

Ensembles de vannes instrumentées SIL 1/2/3 (vanne + actionneur + électrovanne) avec une valeur PFDavg combinée pour l'ensemble de l'élément final. La configuration et le taux de couverture du test de course partielle (PST) sont documentés. Un certificat SIL, délivré par le TÜV ou Exida, est fourni dès l'étape de l'offre commerciale.

Montage ISO 5210/5211 — Coupleur confirmé avant commande

La bride de montage de l'actionneur (ISO 5210 pour mouvement multi-tours / ISO 5211 pour mouvement quart de tour) ainsi que le profil de l'accouplement de tige (carré, rectangulaire ou avec clavette) doivent être vérifiés par rapport au plan de l'interface de montage fourni par le fabricant de la vanne avant toute commande de l'actionneur. Des supports et des accouplements sur mesure sont prévus lorsque le montage selon les normes ISO n'est pas possible.

Our supply standard

Three deliverables on every actuator order that most suppliers ask you to calculate yourself.

Torque sizing calculation — with safety factor — before the PO
01
Torque sizing calculation — with safety factor — before the PO

We obtain the valve manufacturer's torque data sheet — covering breakout torque, running torque, and closing torque at maximum differential pressure and minimum stem packing load. We apply a safety factor of 1.25 to 1.5× on the maximum breakout torque (per the actuator manufacturer's sizing methodology) and confirm that the selected actuator output torque, at the specified minimum supply pressure (pneumatic) or minimum voltage (electric), exceeds the required valve torque with the full safety factor applied. This calculation is delivered as a formal one-page sizing sheet with the quotation. If the calculation fails on the first actuator selection, we go back to the catalogue and propose an alternative before the quotation is issued. Not after you install the actuator and find it cannot move the valve.
Min supply pressure Max ΔP condition SF 1.25–1.5×

ESD battery calculation — number of operations at minimum temperature
02
ESD battery calculation — number of operations at minimum temperature

For battery-backed electric actuators in ESD service, the battery capacity must be sufficient to complete the specified number of full-stroke ESD operations at the minimum ambient temperature specified for the installation — because battery capacity decreases significantly at low temperature, and a battery sized at 20°C may not complete even one ESD operation at −20°C. We calculate the energy demand per ESD operation from the actuator's load (valve breakout torque × stroke) and motor efficiency, multiply by the required number of operations, derate for the minimum temperature, and confirm the battery type and capacity that meets the requirement. Battery specification, replacement interval, and temperature derating are confirmed in writing with the quotation.
Per operation energy Temp derating Replacement interval

SIL final element package — PFD at quotation, PST configuration documented
03
SIL final element package — PFD at quotation, PST configuration documented

For SIL-rated ESD applications, the SIL certificate must cover the complete final element — valve, actuator, and solenoid — not just one component. We supply the combined SIL assessment from a notified body (TÜV or Exida) giving the final element PFDavg at the specified proof test interval, the diagnostic coverage achieved by partial stroke testing (PST), the PST configuration for the positioner or limit switch box, and the common cause failure (CCF) factor β for redundant configurations. The SIL documentation is provided at the quotation stage. Your SIS engineer can verify SIL compliance at the Safety Instrumented Function level before the purchase order is placed — not during site acceptance testing when it is too late to change the specification.

Actuator Sizing Process

How we size every actuator — the five-step process we apply to every valve on your line list.

1

Obtain valve torque data

Request valve manufacturer's torque data sheet covering breakout (initial unseating), running, and seating torque at the maximum differential pressure specified for the line. If the valve has already been ordered, we request the data from the valve manufacturer directly or from the end user's project technical authority.
2

Identify worst-case operating condition

For pneumatic actuators: minimum instrument air supply pressure (typically 3.5 bar where normal supply is 5–6 bar). For electric actuators: minimum supply voltage (typically 90% of nominal per IEC 60034). For battery-backed ESD: minimum battery voltage at end of life and minimum ambient temperature.
3

Apply safety factor

Apply safety factor of 1.25–1.5× to the valve maximum breakout torque (the higher value for modulating control valves and critical ESD valves). The safety factor accounts for manufacturing tolerances in both the valve and actuator, and for degradation of the valve packing over time which increases stem friction and breakout torque.
4

Select actuator and confirm output torque

Select the actuator model from the manufacturer's torque table at the identified worst-case supply condition. Confirm that the actuator's rated output torque at the worst-case supply condition equals or exceeds the required valve torque multiplied by the safety factor. For scotch-yoke actuators, verify at both open and close end-of-travel positions.
5

Issue formal sizing calculation

Issue a formal one-page sizing calculation sheet showing: valve tag, valve torque data reference, worst-case supply pressure/voltage, required torque with safety factor, selected actuator model, actuator rated output torque at worst-case supply. Delivered with the commercial quotation for client review before the purchase order is placed.

Why torque sizing matters — the failure mode if you skip it

An actuator that is under-sized for the valve torque will fail to complete its stroke when the valve packing is loaded, the differential pressure is at maximum, or the supply pressure drops below nominal. For an ESD ball valve, this means the valve fails to close in an emergency. For a control valve, it means the process variable cannot be controlled. Both failure modes are preventable by correct sizing. Global Trading provides the sizing calculation as a standard deliverable — not as an optional extra — because the consequences of incorrect sizing are detected too late to correct without cost.

Mounting compatibility — ISO 5211 confirmation before the order

Before the actuator is ordered, we confirm the ISO 5211 mounting flange size (F05 through F40 for quarter-turn) or ISO 5210 stem category (multi-turn) against the valve manufacturer's top-works drawing. The stem coupler profile — square drive, rectangular drive, or round shaft with keyway — is confirmed from the valve dimensional drawing. If the valve does not have an ISO 5211 mounting pad, a custom bracket and coupler are designed, dimensioned, and submitted to the client for approval before fabrication. Bracket and coupler dimensional drawings are issued as part of the actuator package documentation.
