Features
• Used to operate dampers and 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.
• Replace M445A,D; M845A,C,E; and M865B motors.
• Available with factory-installed transformers, or an internal transformer can be added in the field.
• Oil-immersed motor and gear train provide reliable performance and long life.
• Provide NEMA 3 weather protection with wiring box, when mounted upright.
• Electrically normally closed (at closed position when control signal is at minimum level) and rotate clockwise to open with a signal increase.
• Integral helical spring that returns the motor shaft to the normal position (fully closed for M4185 and M8185; fully open for M4186) on power interruption.

They are designed to operate dampers or valves in applications where it is necessary or desirable for the controlled element to return to its starting position in the event of a power failure or interruption.
Features
Fixed torque throughout the entire voltage range.
Integral spring return returns motor to normal position when power is interrupted.
Integral junction box provides NEMA 3 weather protection if motor is mounted in the upright position.
Motor and circuitry operate from 24 Vac.
Quick-connect terminals are standard–screw terminal adapter is available.
Adapter bracket for matching shaft height of older motors is available.
Motors have field adjustable stroke (90 to 160 degrees).
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.
Motors can operate valve linkages from the power end or auxiliary end shafts for normally closed or normally open valve applications.
All models have dual shafts (slotted and tapped on both ends).
