Overview
EN ISO 5210:2017/prA1 (ISO 5210:2017/DAM 1:2022) is Amendment 1 to the international standard ISO 5210:2017, published under CEN parallel processing. The amendment updates requirements for multi-turn valve actuator attachments (the mechanical interface between multi-turn actuators and valve shafts). It is published as a draft amendment in 2022 and adds a new normative annex that addresses the design and dimensioning of keys and keyways, a primary torque-transfer method for actuator-to-valve connections.
Key Topics
- Scope of the amendment: Revisions to clauses 7.3 and 7.5 to reference Figures/Tables and the new Annex B for Groups B and D assemblies.
- Annex B (normative): Introduces detailed guidance on the forms, dimensions and tolerances of keys and keyways used to transfer torque from actuator to valve shaft. This annex was added because the earlier reference standard (ISO R773:1969) has been withdrawn.
- Key and keyway forms: Illustrations (Figures B.1–B.3) define accepted form types (e.g., round-ended, square-ended, combination), keyway types (milled, disc-milled, manufacturer-specified) and chamfer/radius recommendations.
- Dimensions and tolerances: Tables B.1 and B.2 provide cross-section sizing, depth guidelines, tolerance zones and related notes for a range of shaft diameters and key sizes. Notes cover fit types (tight/loose), machining recommendations and exceptional cases (e.g., oversized grooves).
- Normative status and patent notice: The amendment is normative and part of the ISO/CEN development process; users are asked to report relevant patent rights during the approval stage.
Applications
This amendment is directly applicable to professionals who design, manufacture, specify or maintain valve-actuator interfaces:
- Valve manufacturers and actuator suppliers - to ensure mechanical compatibility and interchangeability of multi-turn actuator attachments.
- Mechanical design engineers - for accurate selection and dimensioning of keys/keyways to achieve reliable torque transmission.
- Procurement and quality teams - to write and verify technical specifications and inspection criteria.
- Maintenance and asset managers - for correct replacement parts and safe shaft/key assembly procedures.
Practical benefits include enhanced compatibility, reduced risk of drive failures, clearer manufacturing tolerances, and consistent torque transfer across valve-actuator assemblies.
Related Standards
- ISO 5210:2017 (base standard for multi-turn valve actuator attachments) - this amendment updates specific clause references and adds Annex B.
- Note: ISO R773:1969 has been withdrawn; Annex B provides a contemporary basis for keys and keyways in this context.
Keywords: EN ISO 5210, multi-turn valve actuator attachments, valve actuator couplings, keys and keyways, torque transfer, valve manufacturers, actuator manufacturers, ISO 5210 amendment.

B.1 Basis for keys and keyways dimensioning
With ISO R773: 1969 being withdrawn, there is currently no international standard defining keys and
keyways available. Since for Group B (see 7.3) and Group D (see 7.5), keys and keyways are the means
to transfer torque from the actuator to the valve, information on design and dimensions is given in
Annex B.
B.2 Key and keyway forms
Forms for key and keyway shall fulfill the requirements given in Figure B.1 to Figure B.3.
Keys and keyways according to low patterns are not described in this Annex.
Bolts for retaining of keys, slants for disassembly of keys and holes for spiral pins are common with
larger key sizes, but are not described in this Annex.
