Belimo NKRQX24-MFT Actuator
The Belimo NKRQX24-MFT Actuator is a high-speed, electronic fail-safe actuator engineered for precise control in critical HVACR valve applications. Operating on AC/DC 24V, this 54 in-lb unit utilizes Multi-Function Technology (MFT), allowing contractors to field-configure control signals, feedback, and running times to meet specific system requirements. Unlike standard spring-return models, this configurable electronic actuator uses an internal capacitor to drive the valve to its fail-safe position during a power loss, with a rapid fail-safe response time of less than 4 seconds. With a standard running time of 4 seconds for a 90° stroke (adjustable from 4 to 10 seconds), it is ideal for high-cycling environments where speed and modulating control accuracy are non-negotiable. The NEMA 2/IP54 rated housing ensures durability in mechanical rooms, while the external manual override button allows for quick commissioning and troubleshooting without specialized tools.
Technical Benefits for Contractors- Flexible Field Configuration: MFT allows for custom input signals (0-10 VDC, 2-10 VDC, 4-20 mA) and feedback settings to match any controller.
- High-Speed Operation: Fast 4-second stroke time prevents system lag in critical cooling or heating loops.
- Reliable Fail-Safe: Electronic capacitor technology provides a programmable fail-safe direction (Normally Open or Normally Closed) without the mechanical weight of traditional springs.
- Efficient Power Usage: Low holding power consumption of only 3W reduces long-term operational costs and transformer sizing requirements.
- Simplified Installation: Universal spindle clamp and selectable direction-of-rotation switches minimize time on the job site.
Can the NKRQX24-MFT be used for both damper and valve applications?
While this specific model is optimized as a valve actuator, its MFT logic can be configured for various 54 in-lb torque requirements. Check spindle compatibility for non-valve applications.
How do I change the fail-safe direction?
The fail-safe direction is easily selectable via a 2-position switch on the actuator housing, allowing you to choose the return-to-zero or return-to-one position upon power loss.
What happens if the power cycles quickly?
The internal capacitor system is designed for rapid recharging, ensuring the electronic fail-safe is ready for the next event shortly after power restoration.
