• 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.
• Visual position indicator.
• Direct a
cting or reverse acting control mode available on
proportional models.
• Rotation limiting available.
• Rugged die-cast housing.
• MS40-7043: plenum rated cables.
• MS41-7xxx equipped with manual override.
