This document specifies the requirements for the attachment of multi-turn actuators to valves.
Throughout this document, “actuator” can be understood as “actuator and/or gearbox” providing a multi-turn and/or linear output.
— 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.
