DIN EN ISO 5210:2017-08

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: - flange dimensions necessary for the attachment of part-turn actuators to industrial valves [see Figure 1 a)] or to intermediate supports [see Figure 1 b)]; - 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.
