Valve Linkages

Application

The AV-601 valve extension kit is used to increase the
allowable ambient temperature range of MA, MF,
MP-5X1X-XXX, MPR-5X1X and MP-541X Series actuators. The
MF-5X1X, 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.

Electric/Electronic Valve Linkage

Specifications

• Kit consists of an extension coupling and a spacer.

• Dimensions: Add 2-1/32 in. (52 mm) to the “E” dimension for the
valve assembly using an AV-601 linkage extension. Refer to
complete dimensions:

- Two-Way Valves, Union End and Flared.

- Two-Way Valves, Screwed and Flanged.

- Three-Way Mixing and Sequencing Valves, Flared.

- Three-Way Mixing and Diverting Valves, Screwed.
