Piping
The valves should be mounted in a weather-protected area in a location that is within
the ambient limits of the actuator. Allow sufficient room for valve with actuator and for
service. Please allow 12” for complete actuator/linkage removal. The G6/G7 preferred
mounting position of the valve is with the valve stem vertical above the valve body,
for maximum life. However, the assemblies can be mounted with valve stem vertical
above the valve or up to 45 degrees in relation to the horizontal pipe. The actuators
should never be mounted underneath the valve, as condensation can build up and
result in a failure of the actuators. Do not reverse flow direction.

• Torque min. 180 in-lb
• Control fixed, 0 to 135 Ω input, or Honeywell series 90 (fixed)
• Feedback 2 to 10 VDC (DEFAULT)
Application
For proportional modulation of dampers and control valves in HVAC systems. The
AFX24-MFT95-X1 provides mechanical spring return operation for reliable fail-safe
application.
Default/Configuration
Default parameters for 0 to 135 Ω Input applications of the AFX24-MFT95-X1 actuator
are assigned during manufacturing. If required, custom versions of the actuator can be
ordered. However the control input cannot be modified via MFT PC tool software. The
parameters noted in the Technical Data table are variable.
These parameters can be changed by three means:
• Pre-set configurations from Belimo
• Custom configurations from Belimo
• Configurations set by the customer using the MFT PC tool (version 3.4 or higher)
software application.

The actuator uses a brushless DC motor which is controlled by an Application Specific
Integrated Circuit (ASIC) and a microprocessor. The microprocessor provides the
intelligence to the ASIC to provide a constant rotation rate and to know the actuator’s
exact position. The ASIC monitors and controls the brushless DC motor’s rotation and
provides a Digital Rotation Sensing (DRS) function to prevent damage to the actuator
in a stall condition. The position feedback signal is generated without the need for
mechanical feedback potentiometers using DRS. The actuator may be stalled
anywhere in its normal rotation without the need of mechanical end switches.
The AFX24-MFT95-X1 is mounted directly to control shafts up to 1.05" diameter by
means of its universal clamp and anti-rotation bracket. A crank arm and several
mounting brackets are available for damper applications where the actuator cannot be
direct coupled to the damper shaft. The spring return system provides minimum
specified torque to the application during a power interruption. The AFB24-MFT95,
AFX24-MFT95 actuator is shipped at +5° (5° from full fail-safe) to provide automatic
compression against damper gaskets for tight shut-off.

Technical Data
The AFX24-MFT95-X1 actuator provides 95° of rotation and is provided with a
graduated position indicator showing 0° to 95°. The actuator will synchronize the 0°
mechanical stop or the physical damper or valve mechanical stop and use this point
for its zero position during normal control operations. A unique manual override allows
the setting of any actuator position within its 95° of rotation with no power applied.
This mechanism can be released physically by the use of a crank supplied with the
actuator. When power is applied the manual override is released and the actuator
drives toward the fail-safe position.

WARNING
G Live Electrical Components!
During installation, testing, servicing and troubleshooting of this product, it may be
necessary to work with live electrical components. Have a qualified licensed electrician or other
individual who has been properly trained in handling live electrical components perform these
tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.
5
Actuators with plenum rated cable do not have numbers on wires; use
color codes instead. Actuators with appliance cables are numbered.
21
Provide overload protection and disconnect as required.
22
Actuators and controller must have separate transformers.
23
Consult controller instruction data for more detailed information.
24
Resistor value depends on the type of controller and the number of actuators.
No resistor is used for one actuator. Honeywell® resistor kits may also be
used.
