Modutrol IV Motors
M4185 Line Volt; M8185 Low Volt Two-Position Modutrol IV™ 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 eld adjustable stroke (90 to 160 degrees)
Motors are designed for either normally open or normally closed
valves and damper
Integral auxiliary switches are available factory mounted, or can be
eld 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)
