Technical requirements of the MSS SP-101 standard for part-turn actuators
The MSS SP-101 standard defines key engineering parameters for interfacing part-turn actuators with industrial valves. The document establishes unified mounting dimensions and operational characteristics for FA-type flange connections and actuator elements supplied as standalone units. The use of these specifications by EV Group China specialists ensures full equipment compatibility and high reliability of control assemblies within automated systems.
Scope and standardization
The regulation covers requirements for the mechanical coupling of the actuator and the valve, ensuring the interchangeability of components from different manufacturers. The use of standardized mounting interfaces allows for the optimization of equipment integration processes during the design phase of process lines. EV Group China experts recommend strictly adhering to the specified tolerances to prevent misalignment and premature wear of actuator mechanisms during operation in industrial environments.
