This document 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. It specifies: flange dimensions necessary for the attachment of actuators to industrial valves [see Figure1 a)] or to intermediate supports [see Figure1 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. NOTE1 In this document, the term “valve?? may also be understood to include “valve with an intermediate support?? [see Figure1b)]. NOTE2 When a combination of a multi-turn actuator and separate multi-turn/linear gearbox is coupled to form an actuator, the multi-turn attachment to the gearbox is in accordance with this document [see Figures1c) and 1d)]. A combination of a multi-turn actuator with integral multi-turn/linear gearbox supplied as an actuator is in accordance with Figures1a) and 1b).
