The Honeywell M8185D1006 Modutrol IV motors are 2-position (line- and low-voltage per motor control) spring-return motors. 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 
 
The Honeywell actuator M8185D1006 contains fixed torque throughout the entire voltage range. The integral spring return returns motor to normal position when power is interrupted and the integral junction box provides NEMA 3 weather protection if motor is mounted in the upright position. The motor and circuitry operate from 24 Vac. Quick-connect terminals are standard and a screw terminal adapter is available, as is an adapter bracket for matching shaft height of older motors is available. Motors have field adjustable stroke (90 to 160 degrees) and are designed for either normally open or normally closed valves and dampers. The integral auxiliary switches are available factory mounted, or can be field added. The motors can operate valve linkages from the power end or auxiliary end shafts for normally closed or normally open valve applications. The M8185D1006 has dual shafts (slotted and tapped on both ends).
