Auxiliary Switch
Max 2A, adjustable cam position (663 actuator
does not have Aux. switch)
Optional
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.
Mounting & Installation:
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.
