Louver and Damper Actuators
Model: FXMBB
Type A (120VAC) Belimo
On-off, spring return safety, 100 to 240 VAC
Torque min. 18 in-lb, for control of air dampers
Application
For on-off, fail safe control of louvers and dampers in HVAC
systems. Actuator sizing should be done in accordance with the
damper manufacturer’s specifications. Control is on-off from an
auxiliary contact, or a manual switch.
The actuator is mounted directly to a damper shaft from 1/4”
up to 1/2” in diameter by means of its universal clamp, 1/2”
shaft centered at delivery. A crank arm and several mounting
brackets are available for applications where the actuator
cannot be direct coupled to the damper shaft.
Operation
The FXMBB series actuators provide true spring return operation for reliable fail-safe application and positive close off on air
tight louvers and dampers. The spring return system provides
consistent torque to the damper with, and without, power
applied to the actuator. The FXMBB series provides 95° of
rotation and is provided with a graduated position indicator
showing 0° to 90°. The actuator may be stalled anywhere in its
normal rotation without the need of mechanical end switches.
Power consumption is reduced in holding mode. The actuator
is double insulated so an electrical ground connection is not
necessary.
Safety Note: Screw a conduit fitting into the actuator’s bushing.
Jacket the actuator’s input and output wiring with suitable
flexible conduit. Properly terminate the conduit in a suitable
junction box.

ACCESSORIES
Louver and Damper Actuators
Model: FXMBG
Type C (24VAC)
On-off, spring return safety, 24 V
Torque min. 60 in-lb, for control of air dampers
Application
For on-off, fail safe control of louvers and dampers in HVAC
systems. Actuator sizing should be done in accordance with the
damper manufacturer’s specifications. Control is on-off from an
auxiliary contact, or a manual switch.
The actuator is mounted directly to a damper shaft up to 1/2” in
diameter by means of its universal clamp, or up to a 1.05”
jackshaft by removing the clamp insert. A crank arm and
several mounting brackets are available for applications where
the actuator cannot be direct coupled to the damper shaft.
Operation
The FXMBG series actuators provide true spring return operation for reliable fail-safe application and positive close off on air
tight louvers and dampers. The spring return system provides
consistent torque to the damper with, and without, power
applied to the actuator. The FXMBG series provides 95° of
rotation and is provided with a graduated position indicator
showing 0° to 95°. The actuator may be stalled anywhere in its
normal rotation without the need of mechanical end switches.
Five Year Warranty

conditional warranty applies. Under this conditional warranty, the consequences of ordinary wear
and tear, damage due to negligence or improper use, or other causes beyond our control are
excluded from warranty coverage. Attempts at field repair or modifications will null and void
warranty. Products found defective will be replaced or repaired at seller’s discretion. Seller is not

The FXMBH uses a brushless DC motor which is controlled by
an Application Specific Integrated Circuit (ASIC). The ASIC
monitors and controls the actuator’s rotation and provides a digital rotation sensing function to prevent damage to the actuator
in a stall condition. The actuator may be stalled anywhere in its
normal rotation without the need of mechanical end switches.
