Belimo NRX24-SR-T-N4 Actuator
The Belimo NRX24-SR-T-N4 is a professional-grade non-spring return actuator engineered for high-performance modulation in demanding HVACR environments. This direct-coupled actuator delivers a reliable 70 in-lb torque, making it a staple for contractors managing proportional control across NEMA 4X rated installations. Built for versatility, the unit operates on a standard 24VAC/DC power supply and accepts a 2-10 VDC control signal, ensuring seamless integration with modern building automation systems. The inclusion of a screw terminal strip simplifies field wiring compared to traditional cable models, while the IP66/67 rated enclosure provides superior protection against moisture and debris. Whether you are retrofitting existing Characterized Control Valves (CCV) or implementing new proportional valve actuators, this Belimo NEMA 4 actuator ensures precise positioning with a 90-second run time and manual override capability. Its robust die-cast aluminum housing is designed to withstand harsh outdoor or industrial conditions without compromising signal accuracy.
Key Benefits:
- Rugged NEMA 4X / IP66/67 Protection: Tested to withstand severe weather, wash-down environments, and corrosion, ensuring long-term HVAC control reliability.
- Precise Proportional Modulation: Responds accurately to 2-10 VDC signals for fine-tuned flow control in chilled or hot water systems.
- Contractor-Friendly Installation: Featured screw terminal connections allow for direct 26 to 14 GA wire attachment, reducing the need for additional junction boxes.
- Energy Efficient Operation: Low power consumption (3.5W running, 0.6W holding) reduces the load on 24V transformer sizing.
- Manual Override: Integrated external push button allows for manual positioning of the valve during commissioning or power loss.
Common Questions:
- Can I use this actuator with a 4-20 mA signal? Yes, the Belimo NRX24-SR-T-N4 can be adapted for 4-20 mA control by adding a 500 Ω ZG-R01 resistor in parallel with the signal input.
- Is this suitable for outdoor use? Absolutely. The UL Enclosure Type 4X rating is specifically designed for outdoor applications, protecting the internal motor from wind-blown dust and rain.
- Can these actuators be wired in parallel? Yes, non-spring return actuators may be connected in parallel provided the transformer capacity and input impedance (100 kΩ) are properly accounted for in your actuator wiring.
