AV-601 Extension for MA, MP
5x1x-xxx, MPR-5x1x and MP-
541x
Application
The AV-601 linkage extension kit is used to increase the allowable ambient tem-
perature range of MA, MP-5x1x-xxx, MPR-5x1x and MP-541x Series actuators.
The MP-541x and MPR-5x1x Series of actuators require the AV-601 extension.
This kit provides thermal insulation between the valve and the actuator. It does
not insulate the actuator from radiant or convective heat transfer.
Specifications
Kit consists of an extension coupling and a spacer.
Dimensions: Add 2-1/32" (52 mm) to the “E” dimension for the valve assembly us-
ing an AV-601 linkage extension. Refer to complete dimensions in the separately
available Wiring, Dimensions and Reference document F-28125 from the Exchange
