ISO 5210 Flange - Multi-turn actuator to valve attachment (DIN 3338)

 

This Standard specifies the requirements for the attachment of multi-turn actuators to valves. Throughout this Standard, "actuator" may be understood as "actuator and/or gearbox".

This standard specifies:
• flange dimensions necessary for the attachment interface of actuators to general purpose industrial valves; valves or to intermediate supports;
• 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 Standard.
