Abstract
This document specifies the relevant requirements for the connection of some rotary drive devices connected to industrial valves.
Including:
——The flange dimensions necessary for some rotary drive devices connected to industrial valves [see Figures 1a) and 1c)], or connected to intermediate connecting supports [see Figures 1b) and 1d)];
——The structural form and dimensions of the drive components of some rotary drive devices necessary for connection to the driven components;
——The dimensions of the flange connection surfaces directly connected to industrial valves and the reference torque values of the connecting flanges.
This document applies to the connection dimensions of some rotary valve drive devices and valves.
This document does not apply to the connection dimensions of intermediate supports and valves.
