This European Standard specifies requeriments for the attachment of part-turn actuators, with or without gearboxes, to industrial valves.

This standard specifies:
• flange dimensions necessary for the attachment of part-turn actuators to industrial valves or to intermediate supports;
• driving component dimensions of part-turn actuators necessary to attach them to the driven components;
• reference values for torques to interfaces and for couplings having the dimensions specified in this standard.
