Actionator Electric Positioning Motors
For Demanding Industrial Control Applications
® Motor is an industrially rated, high-torque motor, designed for accurate control and precise positioning of control valves, dampers, louvers and butterfly valves. It is the motor of choice for demanding industrial control processes, such as fossil fuel and heating applications.
The Actionator Motor controls a process’s final control element (valve, damper, louver), increasing or decreasing/opening or closing in response to the output signal from the process controller. Rotary Actionators are set at the factory for 150 degrees of rotation and are field adjustable. The .5 by .5 inch (12.7 mm x 12.7 mm) square output shaft has a crank arm that connects to a linkage rod/ball joint to position the air damper, louver, vane, or butterfly valve for fuel/air modulation in a combustion burner system.
• Heavy-duty construction: U/L and CSA enclosure rating #4, NEMA 3, sealed die-cast aluminum case, “Oâ€-ring-sealed motor shaft
• High torque: up to 25 ft/lbs torque rating
• Ambient temperature rate -20
• Timing: model-dependent, from 6.25 to 120 seconds
• Rotary or Linear output models
• Control form of twoposition ON-OFF, Currentor Position-proportional
• Wide range of motor repositions
• Motor position locked on power interruption
• Adjustable crank arm included with each motor
• Adjustable end-of-travel and limit switches
• Interfaces with Flame Safeguard motor positioning for high purge rate and low fire start (RM7800E,G,L, RM7840E,G,L, RM7838B)
• M640 for ON-OFF control, SPDT, for use with a twoposition controller with maintain contracts
• M740 for current-proportioning control (4 to 20 mA)
Models M640A, M740A and M940A provide rotary motion from a .5 by .5 inch (12.7 mm x 12.7 mm) output shaft.
Models M640B, M740B and M940B are linear output devices. These can be used to operate slip-stem valves of the direct-acting, reverse-acting or three-way types using suitable linkage.
Stroke: M740A and M940A provide 150 degrees of rotation, factory-set. M640 is adjustable from 10 to 350 degrees.
Thrust: All ‘B’ models are adjustable from .25 to 1.5 inches (6.35 mm to 38.1mm).
