Information About AFB24-MFT-X1

The AFB24-MFT-X1 is part of Belimo’s AFB actuator family and is offered within its RetroFIT+ control valve actuator range. Its galvanized steel and plastic housing incorporates a mechanical position indicator and manual override. Multi-Function Technology allows control characteristics and motor running time to be configured for the connected application. Integration with existing equipment requires compatible valve mounting hardware and a controller signal matching the actuator’s programmed operating mode.

Key Features:

• Programmable control: Uses Multi-Function Technology to adapt operating parameters to application requirements.
• Spring return: Provides mechanical fail-safe movement when electrical power is interrupted.
• Low-voltage operation: Accepts nominal 24 VAC or 24 VDC power.
• Signal flexibility: Supports configurable voltage, pulse-width modulation, on/off, and floating-point control modes.
• Position feedback: Supplies a standard 2–10 VDC output for monitoring actuator position.
• Adjustable running time: Offers a programmable motor travel time range of 70–220 seconds.
• Manual override: Includes a hex crank for positioning during installation or servicing.
• Replacement reference: Listed as the replacement for AFX24-MFT-X1, subject to application compatibility.

The AFB24-MFT-X1 delivers the reliability and precision required for programmable valve positioning and fail-safe operation in building climate control systems.
