ISO 5210:2017

ISO 5210:2017 specifies the requirements for the attachment of multi-turn actuators to valves.
Throughout this document, 'actuator' may be understood as 'actuator and/or gearbox' providing a multi-turn and/or linear output.
ISO 5210:2017 specifies:
- flange dimensions necessary for the attachment of 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 document.
