The Series 41 and Series 81 Modutrol IV Motors are
2-position (line- and low- voltage, respectively) spring-return
motors. They are used to operate dampers or valves in
applications where it is necessary or desirable to have the
controlled element return to the starting position in the event
of power failure or interruption.
FEATURES
• Used to replace M445, M845 and M865 motors.
• Models rated for 25 lb.-in. or 60 lb.-in. torque.
• Integral spring return returns motor to normal position
(open or closed) when power is interrupted.
• Oil immersed motor and gear train for reliable
performance and long life.
• Wiring box provides NEMA 3 weather protection.
• Motor operates from 24 Vac. Models are available
with factory installed transformer, or an internal
transformer can be field added.
• Quick-connect terminals are standard—screw terminal
adapter is available.
• Adapter bracket for matching shaft height of older
motors is standard with TRADELINE motors.
• TRADELINE motors have field adjustable stroke
(90° to 160°).
• Die-cast aluminum housing.
• Motors are designed for either normally open or
normally closed valves and dampers.
• Integral auxiliary switches are available factory
mounted, or can be field added to TRADELINE models.

the power end or auxiliary end shafts for normally
closed or normally open valve applications.
