• Models rated for 60 lb.-in. torque.
• Fixed torque throughout the entire voltage range.
• Integral spring return returns motor to normal position when power is interrupted.
• 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.
