This International Standard specifies the require-ments 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 (see figure 1);
— 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 Inter-national Standard.
NOTE 1 ISO 5211[1] specifies requirements for part-turn valve actuator attachments.
