Electric Actuator On/Off Spring Return Floor 24 Volt 50/60 Hertz

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

• Integral junction box provides NEMA 3 weather protection
• Integral spring return returns motor to normal position when power is interrupted
• Motor and circuitry operate from 24 VAC models available with factory installed transformer or a field added internal transformer
• Spring return motors can operate valve linkages form 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)
• All models have auxiliary switch cams
• Fixed torque throughout the entire voltage range
• Motors are designed for either normally open or normally closed valves and dampers
• Normally open/normally closed valves and dampers
