Scope

This document specifies requirements for the attachment of part-turn actuators, with or without gearboxes, to industrial valves. The attachment of part-turn actuators to control valves in accordance with the requirements of this document is subj ect to an agreement between the supplier and the purchaser. This document specifies: — flange dimensions necessary for the attachment of part-turn actuators to indus trial valves [see Figures 1 a) and 1 c)] or to intermediate supports [see Figures 1 b) and 1 d)] ; — driving component dimensions of part-turn actuators necessary to attach them to the driven components; — reference values for torques for interfaces and for couplings having the dimensions specified in this document. The attachmentofthe intermediate supportto the valve is outofthe scope ofthis document. NO TE 1 I n this document, the term “valve” may also be unders tood to include “valve with an intermediate support” [see Figure 1 b)]. NOTE 2 When a combination of a multi-turn actuator and separate part-turn gearbox is coupled to form a part-turn actuator, the multi-turn attachment to the gearbox is in accordance with ISO 5210:2017, Figures 1 c) and 1 d). Acombination ofa multi-turn actuatorwith integral part-turn gearboxsupplied as a part-turn actuator is in accordance with Figures 1a) and 1b). a) Direct interface b) Intermediate support interface c) Direct interface (when combination of a multi-turn actuator and a gearbox) d) Intermediate support interface (when combination of a multi- turn actuator and a gearbox) Key 1 part-turn actuator 5 gearbox 2 interface (see ISO 5211) 6 interface (see ISO 5210) 3 valve 7 multi-turn actuator 4 intermediate support Figure 1 — Interface between part-turn actuator and valve
