Model Chart
Specifications
TAC DuraDrive overshaft actuators are designed to
provide an economical and reliable solution for
many overshaft damper and ball valve
requirements. All products accommodate shaft
sizes up to 1/2 in. (13 mm) in diameter.
Non-spring return models provide either 35 in-lb
(4 N-m) or 70 in-lb (8 N-m) in proportional control.
Features:
• Floating models controlled by SPDT floating controllers.
• Non-spring return models supply 35 in-lb (4 N-m) or 70 in-
lb (8 N-m) of torque.
• Polymer housing rated for NEMA 2/IP54 and for plenum
use.
• Overload protection throughout stroke.
• Automatically adjust the input span to match the
damper/valve travel.
• Compact size to allow installation in limited space.
• Manual override to allow positioning of dampers and
valves.
• Directly mounts to 1/2 to 3 in. ball valves.
