The Series 90 Modutrol IV Motors are spring return and non-spring return modulating proportional control motors. Use these motors with controllers that provide a Series 90 output to operate dampers or valves.
- 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
- Field addable interface modules can be mounted in the junction box to upgrade the motor to series 70 (electronic) control
- Motors are designed for either normally open or normally closed valves and dampers
