The ARA 600 series of motor actuators replaces
the Series 60 of 24V motor actuators mounted to
ESBE 3 way and 4 way rotary valves. Incorporated
into the redesign of the ARA motor actuators are
improvements in the mounting and operation
of the motor actuator resulting in a simpler and
quicker installation.
These redesigned direct mounted motor actuators
are capable of mounting to the new VRG styles of
3 & 4-way rotary valves. In addition, the ARA 600
series are also backward compatible to the older
MG and G series of valves.
The ARA 600 series is available in oating 3-point
with or without an auxiliary switch and proportional,
which cross over to the Series 60 actuators.
However there are additional varieties of actuators
to select from a 2-point actuator to di erent run
time options. These variety of selections provide
exibility in application selecting.

Mounting & Installation:
4
The actuator should be mounted with the ESBE rotary valve stem in either a horizontal position or
pointing upwards. The actuator should not be installed in a downward orientation to reduce the possible
contact of water with the actuator. Included with the actuator is the mounting hardware necessary to
mount the electric motor actuator to an ESBE rotary mixing valves; MG, G, and VRG series.
Orientation
With the white drive sleeve the ARA actuator can be installed on older MG and G series of valves and
also current VRG valves. The orientation of the drive sleeve determines the style of valve the actuator
will mount to.
When placing the actuator in manual operation power should be turned o to the actuator. In the
event the actuator is powered and is left in a manual position, the result could lead to the internal
damage of the actuator.
To manually operate the ARA Series actuator, slightly pull out on the large indicator knob. With it
pulled out, rotate the knob to the left or right to manually operate the valve. To return the actuator to
automatic operation, rotate the knob to the position prior to manual operation and push the knob into
the actuator.
