Information About NMX24-MFT-X1
The NMX24-MFT-X1 is part of Belimo’s NM series of compact valve actuators engineered for flexible and reliable hydronic control. It incorporates Belimo MFT multi-functional technology, allowing field configuration of control signals, operating ranges, and actuator behavior to match specific system requirements. The actuator is designed for non fail-safe applications where continuous powered positioning is required without spring return action. Electronic overload protection throughout the full rotation range ensures dependable operation and long service life.
Key Features
- Non Spring Return Operation: Provides powered valve positioning without fail-safe spring action for applications where return on power loss is not required.
- MFT Programmable Control Technology: Supports multiple control modes including 2…10 V, 4…20 mA, PWM, on/off, and floating point for broad system compatibility.
- Configurable Control Range: Adjustable start and end points allow precise alignment of actuator response with building automation requirements.
- Integrated Position Feedback: Supplies a variable 2…10 V feedback signal for continuous valve position monitoring and closed-loop control.
- Electronic Overload Protection: Protects the actuator throughout the full 0…95° rotation range against obstruction or excessive load.
- Selectable Direction Of Motion: Motor rotation direction can be configured via onboard switch to accommodate different mounting orientations.
- Manual Override Push Button: Enables local valve positioning during commissioning, testing, or maintenance without tools.
The NMX24-MFT-X1 delivers the reliability and precision required for programmable modulating valve control in non fail-safe HVAC hydronic applications.
