Industrial valves. Multi-turn valve actuator attachments Ingestion-build-68772 Arc voltage limits1 Scope 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 Figure 1 a)] or to intermediate supports [see Figure 1 b)]; those driving component dimensions of actuators which are necessary
