This document specifies the requirements for connecting multi-turn actuators to valves. Throughout this document, the term “actuator” may be understood to mean “actuator and/or reducer” providing multi-turn and/or linear output. It prescribes: — the dimensions of the flanges necessary for the connection of actuators to industrial valves [see Figure 1 a)] or to intermediate supports [see Figure 1 b)]; — the dimensions of the actuator driving elements necessary for their coupling to the driven elements; — the torque and thrust reference values for flanges having the dimensions specified in this document.
