Full title and description

ISO 12490:2011 — Petroleum and natural gas industries — Mechanical integrity and sizing of actuators and mounting kits for pipeline valves. This International Standard defines requirements and guidance for ensuring the mechanical integrity and correct sizing of actuators and associated mounting kits fitted to pipeline valves.

Abstract

ISO 12490:2011 specifies requirements for mechanical integrity and the sizing of actuators used on valves manufactured under ISO 14313 and API Specification 6D. It applies to electric, pneumatic and hydraulic actuators (including mounting kits) installed on pipeline valves, and explicitly excludes actuators for control valves, valves used for regulation, sub-sea service, handheld powered devices, stand-alone manual gearboxes, instrument tubing and actuator control equipment.

Scope

The standard is intended for actuators and their mounting kits fitted to pipeline valves manufactured to ISO 14313 and API Specification 6D. It covers mechanical integrity checks and methods for sizing actuators to ensure safe, reliable operation under expected pipeline conditions. It does not apply to actuators on control/regulating valves, subsea applications, handheld powered devices, stand-alone manual gearboxes, or associated instrumentation and control equipment.

Key topics and requirements

• Principles for mechanical integrity of actuators and mounting kits.
• Sizing methodology to ensure actuators provide required torque/force for valve operation under design conditions.
• Applicability to electric, pneumatic and hydraulic actuators used on pipeline valves.
• Design and installation considerations for mounting kits to maintain actuator–valve interface integrity.
• Exclusions and limitations (control valves, subsea service, handheld devices, instrument tubing, etc.).
• Requirements for documentation, verification and lifecycle review of actuator installation and performance.

Typical use and users

Used by pipeline operators, valve and actuator manufacturers, engineering consultants, integrity and maintenance teams, procurement specialists and conformity assessors involved in selection, installation and verification of actuators and mounting kits for pipeline valves in the oil and gas sector.

Related standards

Most directly related to ISO 14313 and API Specification 6D (valve manufacture and pipeline valve requirements). It is developed under ISO/TC 67/SC 2 and, at the time of the ISO record, an updated draft (ISO/DIS 12490) was under development to replace or revise the 2011 edition.
