MSS SP-102 Standard: Requirements for connecting dimensions and characteristics of multi-turn actuators

Technical purpose and scope of the MSS SP-102 standard

This normative document establishes uniform requirements for mounting interfaces and performance indicators of multi-turn actuators intended for integration with general industrial shut-off and control valves. The technical regulations within the framework of this standard apply exclusively to actuators supplied as independent assembly units, ensuring the unification of connecting dimensions, torques, and flange connection sizes for their correct coupling with valves in field conditions.
