24 Vdc supply and receives a 0 to 10 Vdc or a 4 to 20 mA control signal to proportionally
control a valve. This actuator is designed to work with Powermite 599 MT Series
terminal unit valve with a 7/32-inch (5.5 mm) stroke.
• Maintenance-free with reversible motor.
• Position indicator.
• UL listed for plenum installations.
• 0 to 10V or 4 to 20 mA.
• LED status indicator.
• Auto calibration
• Position output signal 0 to 10 Vdc.
• Manual positioning knob with stroke indication allows for repositioning.
• Mechanical spring returns the valve to its normal (fail-safe) position in power-off
conditions (SAS61.33U Actuator only).
For use in small to medium HVAC installations with Powermite 599 Series terminal unit
valves with a 7/32-inch (5.5 mm) stroke requiring a minimum of 90 pounds force (400N).
They can be used in liquid and low pressure steam service applications.
