Overview

ISO 12490 is an International Standard for the oil and gas industries including lower carbon energy that addresses the mechanical integrity and sizing of actuators and mounting kits for pipeline valves. It applies to electric, pneumatic, hydraulic, and electro-hydraulic actuators used on valves conforming to ISO 14313 and API Specification 6D.

This standard is especially relevant for organizations involved in pipeline transportation systems, where reliable actuator selection, installation, and marking support safe and consistent valve operation. It also reflects the need to align with the current API 6DX, 3rd edition (2025), while adding ISO-specific requirements for conformity and identification.

ISO 12490 is intended for actuator assemblies that are built as a single unit or assembled from modules. It also addresses the responsibilities of third-party suppliers such as manufacturers, distributors, stockists, value-add centers, and integrators.

Key Topics

Mechanical integrity and sizing

ISO 12490 provides requirements for the design, mechanical integrity, and sizing of actuators used on pipeline valves. This helps support dependable performance across the valve-actuator assembly and strengthens consistency in actuator selection.

Scope of actuator types

The standard covers:

  • Electric actuators
  • Pneumatic actuators
  • Hydraulic actuators
  • Electro-hydraulic actuators
  • Mounting kits and related components

Marking and identification

The document includes clear actuator marking requirements. In addition to the applicable API 6DX markings, “ISO 12490” must be marked on the actuator nameplate. This supports traceability and conformity assessment in procurement and manufacturing.

Supplier and conformity obligations

ISO 12490 states that the manufacturer is responsible for compliance with the document and must provide a statement of conformity. The standard also includes added expectations for:

  • Assembly of modules by the supplier
  • Testing of actuators by the supplier
  • Functional testing of the valve and actuator assembly

Applications

ISO 12490 is useful in projects and operations involving pipeline valves where actuator reliability and correct sizing are critical. Common applications include:

  • Pipeline transportation systems
  • Valve actuator procurement and specification
  • Mechanical integrity verification
  • Factory assembly and testing
  • Nameplate marking and product identification
  • Quality assurance for valve-actuator packages

The standard is particularly valuable for manufacturers and supply chain partners that need a clear framework for delivering compliant actuator solutions for pipeline service.

Related Standards

ISO 12490 is closely linked to the following standards:

  • API 6DX, 3rd edition (2025) - Actuators and Mounting Kits for Valves
  • ISO 14313 - Pipeline valves for oil and gas industries
  • API Specification 6D - Specification for valves

Together, these standards support a broader framework for pipeline valve performance, actuator compatibility, and conformity in the oil and gas sector and related lower carbon energy applications.

L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux
de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général
confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (IEC) en ce qui concerne la normalisation électrotechnique.
