Actuator Specifications and Valve Assembly Mounting Dimensions
Valve Assemblies with MF41-6043, MS41-6043, MF41-6083, and MS41-6083 Actuators
Note: Standard Linked Valve Assemblies use the basic MF41-6043, MS41-6043, MF41-6083, and MS41-6083 actuators.
Specifications for the non-standard Mx41-6043/6083-502, -510, -520, -522 actuators are provided here for reference. Linked
Valve Assemblies using these non-standard actuators may be special-ordered by contacting the factory or field-mounted using
the AV-60x linkage kit for globe valve assemblies.
