FEATURES:

• Replaces M734H,J,; M744S,T,Y; and M745L,S,T,Y Motors. 
• Non-spring return motors.
•  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. 
• Most motors have field adjustable stroke (90° to 160°).
• Die-cast aluminum housing.
• Integral auxiliary switches are available factory mounted, or can be field added.
• Nominal timing standard of 30 seconds (90° stroke), and 60 seconds (160° stroke). Other timings available.
• Spring return motors can operate valve linkages from 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.
