This International Standard specifies the requirements for the attachment of multi-turn actuators to valves.

Throughout this International Standard, "actuator" may be understood as "actuator and/or gearbox". It specifies

— those flange dimensions which are necessary for the attachment interface of actuators to general purpose industrial valves;

— those driving component dimensions of actuators which are necessary to attach them to the driven components;

— reference values for torque and thrust for flanges having the dimensions specified in this International Standard.

NOTE 1 ISO 5211 specifies requirements for part-turn valve actuator attachments.
