Users often ask: electric and pneumatic actuators each have Chinese national standards — do international standards exist? The answer is yes. This article systematically lists the current Chinese national standards (with official free full-text reading links) and the international standards (ISO/IEC/EN), and maps the correspondence between the two systems.

International standardization runs along three lines: connection-interface standards (how actuators mount to valves), positioner-mounting standards for control valves, and basic requirements with duty classification for actuators; functional safety has its own SIL framework.
| International standard | Content | Relation to GB standards |
|---|---|---|
| ISO 5210 (current 2023 edition) | Multi-turn valve actuator attachments | International counterpart of GB/T 12222 |
| ISO 5211 (current 2023 edition) | Part-turn valve actuator attachments | International counterpart of GB/T 12223 |
| IEC 60534-6-1 | Industrial-process control valves — Part 6-1: Mounting details for attachment of positioners to control valves (linear actuators) | No one-to-one GB counterpart; common for export equipment |
| IEC 60534-6-2 | Same (rotary actuators) | Same |
| EN 15714-1:2009 | Industrial valves — Actuators — General | European standard |
| EN 15714-2:2009 | Electric actuators for industrial valves — Basic requirements | Defines duty classification of electric actuators (S2 short-time, S4 intermittent etc.), widely cited for the European market |
| EN 15714-3:2022 | Pneumatic part-turn actuators for industrial valves — Basic requirements | European benchmark for selection and testing of pneumatic actuators |
| IEC 61508 / IEC 61511 | Functional safety of E/E/PE safety systems; safety instrumented systems for the process industry | International basis for SIL 2/SIL 3 certification |
Availability: ISO and IEC standards are paid publications — search the ISO store or IEC Webstore; EN standards are published by CEN and sold through member bodies such as BSI and DIN.
| National standard | Corresponding / related international standard |
|---|---|
| GB/T 12222-2023 (multi-turn attachments) | ISO 5210 |
| GB/T 12223-2023 (part-turn attachments) | ISO 5211 |
| GB/T 4213-2024 (pneumatic control valves) | No one-to-one counterpart; leakage classes comparable to ANSI/FCI 70.2 |
| GB/T 26155 series, GB/T 28270 (intelligent electric) | No direct ISO counterpart; functional safety per IEC 61508/61511 |
| EN 15714-2 duty classes (S2/S4) | Domestic catalogues commonly use the same S2/S4/S5 duty notation |
All national standards can be read free of charge on the official open system (links above); companion standards such as the GB/T 3836 series are searchable on the same system. For catalogues and manuals see our manual collection or contact us.
