Belimo nru24-sr Spring Return Rotary Actuator

Belimo NR24-SR spring-return rotary actuator provides 10 Nm of torque to drive mixing valves in HVAC and hydronic systems, with spring-return action to fail-safe position on power loss. It runs on AC or DC 24 V and accepts a 2-10 V control signal for modulation, delivering a travel time of 140 seconds. The actuator is IP40 rated for indoor mounting and is designed for compact installations where 24 V control and 2-10 V signals are used for precise valve positioning. Suitable for retrofit or new installations, the NR24-SR integrates with Belimo valve assemblies to ensure reliable, quiet operation and predictable fail-safe behavior in building automation applications.
