Features
• 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.
• Quick-connect terminals are standard—screw terminal adapter is
available.
• Motors have field adjustable stroke (90° to 160°)
• Die-cast aluminum housing.
• Nominal timing standard of 30 seconds (90° stroke), and 60 seconds (160° stroke).
• 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.
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.
