The Series 41 and Series 81 Modutrol IV Motors are 2-position (line- and low- voltage control, respectively) spring-return motors.

• Models rated for 60 lb.-in. torque.
• Fixed torque throughout the entire voltage range.

• Integral junction box provides NEMA 3 weather protection.
• Motor and circuitry operate from 24 Vac. Models available with factory installed transformer, or a field added internal transformer.
• 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°).
• Die-cast aluminum housing.
• Motors are designed for either normally open or normally closed valves and dampers.
• All models have auxiliary switch cams.
• 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.
