Issue

Replacement of AVUE Mk 1 Actuator installed on VEU, MEU or FEU Mk 2 Unit Control Valve Body due to Actuator obsolescence.

Product Line

Field Devices

Environment

AVUE Mk 1 Actuator installed on VEU, MEU or FEU Mk 2 Unit Control Valve Body.

Cause

AVUE Mk 1 Actuator obsolescence.

Resolution

Replace AVUE Mk 1 Actuator.

AVUE Mk 5 Actuators are not compatible with the VEU, MEU or FEU Mk 2 Unit Control Valve Bodies.

It will therefore be necessary to replace both the AVUE Mk 1 Actuator and the Valve Body on which it is installed.

Replacement products may be selected from the following :-

AVUE Mk 1 Actuator = MZ20A or MZ20A-R

VEU Mk 2 Valve Body (2-port) = VZ219 series of appropriate connection type / size / Kv rating

MEU Mk 2 Valve Body (3-port) = VZ319 series of appropriate connection type / size / Kv rating

FEU Mk 2 Valve Body (4-port) = VZ419 series of appropriate connection type / size / Kv rating

 

N.B.

It should be noted that there may be dimensional variations between the existing and replacement Valve Bodies.
