Industrial valves - Part-turn actuator attachments (ISO 5211:2026)
Scope: This document specifies requirements for the attachment of part-turn actuators, with or without gearboxes, to industrial valves.
The attachment of part-turn actuators to control valves in accordance with the requirements of this document is subject to an agreement between the supplier and the purchaser.
This document specifies:
flange dimensions necessary for the attachment of part-turn actuators to industrial valves [see Figures 1 a) and 1 c)] or to intermediate supports [see Figures 1 b) and 1 d)];
driving component dimensions of part-turn actuators necessary to attach them to the driven components;
reference values for torques for interfaces and for couplings having the dimensions specified in this document.
The attachment of the intermediate support to the valve is beyond the scope of this document.

Industrial valves - Gearboxes for valves (ISO 22109:2026)
Scope: This document specifies basic requirements for gearboxes to operate industrial valves for manual and automated on/off and modulating duties, including manual override gearboxes. It includes guidelines for classification, design and methods for conformity assessment.
This document does not cover gear systems which are an integral part in the design of valves and subsea gearboxes.
Other requirements or conditions of use different from those indicated in this document are agreed between the purchaser and the manufacturer or supplier (first party) prior to order.
