Proportional Actuator
Model Chart
For spring return applications that require
proportional modulation control of dampers and
valves in HVAC systems.
Features:
• 150 lb.-in. (17 N-m) rated torque.
• Direct mount to round or square damper shaft.
• Overload protection throughout rotation.
• True mechanical clockwise or counterclockwise spring
return operation for positive close-off in airtight
applications.
• Oil immersed gear train provides continuous lubrication.
• NEMA 4 housing (IEC IP56).
• Automatic current sensing motor control provides extended
reliability and repeatable timing.
• Visual position indicator.
• Provide proportional control compatible with 2 to 10 Vdc or
4 to 20 mAdc with intergrated resistor.
