This International Standard specifies the requirements for the attachment of multi-turn actuators to valves. Throughout this International Standard, “actuator” may be understood as “actuator and/or gearbox”. It specifies: – flange dimensions necessary for the attachment of part-turn 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 International Standard. NOTE – In this International standard the term “valve” may also be understood to include “valve with an intermediate support” [see Figure 1 b)]. a) Direct interface b) Intermediate support interface Key 1 multi-turn actuator 2 interface ISO 5210 3 Valve 4 intermediate support Figure 1 – Interface between multi-turn actuator and valve DRAFT INTERNATIONAL STANDARD ISO/DIS 5210:2016(
