35 lb-in Direct Coupled Actuators
Product Description
For spring return applications requiring floating, two-position, or
proportional modulation control of dampers and valves in HVAC sys-
tems. Directly mounts to ½"…3" Schneider Electric ball valves.
Features
• Direct mount to round or square damper shaft
• 35 lb-in (4 N-m) torque rating
• Overload protection throughout rotation
• Optional built-in auxiliary switches
• True mechanical clockwise or counterclockwise spring return operation for
reliable, positive close-off in airtight applications
• Visual position indicator
• Direct acting or reverse acting control mode available on proportional models
• Rotation limiting available
• Rugged die-cast housing for NEMA 2/IP54 rating
