Modutrol IV Motors

M4185 Line Volt; M8185 Low Volt Two-Position Modutrol IV™ Series 2 Motors

Series 41 and Series 81 Modutrol IV motors are 2-position (line- and low-voltage per motor control) 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.

• Fixed torque throughout the entire voltage range

• Integral spring return returns motor to normal position in the event of power failure

• 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)
