Belimo NFB24 Spring Return Actuator In-lb On-Off Damper Actuators & Accessories - 24V 60

The Belimo NFB24 is a spring return actuator designed for on-off control of dampers and valves in HVAC systems. This 24-volt actuator delivers 60 in-lb (7 Nm) of torque, providing reliable positioning force for commercial building automation applications.

Key Features:

• Spring return operation for fail-safe positioning during power loss
• 60 in-lb (7 Nm) torque output for dampers and valves up to 15 square feet
• 24V AC/DC power supply for flexible installation
• On-off control with two-position operation
• Direct replacement for legacy NF24 actuators
• Durable construction for long service life in commercial HVAC environments
• Universal mounting configuration for easy retrofits

The NFB24 is engineered as an upgraded replacement for the discontinued Belimo NF24 actuator, maintaining compatibility with existing mounting patterns and electrical connections. The spring return mechanism automatically returns the actuator to its fail-safe position when power is removed, making it ideal for life safety applications and critical ventilation control. Suitable for commercial buildings, laboratories, hospitals, and industrial facilities requiring reliable damper and valve control.
