Multi-Turn Valve Actuator Attachment -- Flange and Driving Component Dimensions and Performance Characteristics

This MSS Standard Practice is intended to provide a basis for the standardization of multi-turn actuator mounting dimensions and performance characteristics necessary for their attachment to general purpose industrial valves.It covers only those actuators supplied by manufacturers as separate components.

This MSS Standard Practice is based, in part, on ISO Standard 5210, Multi-turn Actuator Attachment. It also reflects the common practice of the valve and valve actuator industries in North America today. Therefore, the ratings, sizes, and/or number of flange types in the MSS Standard for the North American market may differ from those of ISO.
