Application
DuraDrive™
Direct Coupled Actuators are designed to
be used in both damper and valve control applications.
The following general instructions are for damper
applications. Refer to the Applicable Literature table for
valve literature.
The MS4X-7XX3 series spring return actuators provide
proportional modulation control of dampers and valves
in HVAC systems.
Features
Proportional models controlled by 6-9 Vdc, 2-10
Vdc, or 4-20 mA with the addition of a 500 ohm
resistor
133 lb-in (15 N-m), 60 lb-in (7 N-m) or 35 lb-in
(4 N-m) of torque
Rugged die-case housings rated for NEMA 2 / IP54
Optional built-in auxiliary switch to provide for
interfacing or signaling
Provides 95° of rotation
Visual position indicator provided
Provides true mechanical clockwise or
counterclockwise spring return operation for reliable
fail safe application and positive close-off in air tight
damper applications
MS40-7043-MPX models controlled by 6-9 Vdc with
auxiliary 20 Vdc power supply provides power to
controllers, replacing MP-5XXX/MPR-5XXX
electrohydraulic actuators
Direct mount to round or square damper shafts
Switch provided for selection of direct or reverse
acting control mode
Rotation limiting available
