Belimo GRB24-MFT-7 24V Non-Spring Return Modulating Actuator

The Belimo GRB24-MFT-7 is a 24V non-spring return (NSR) modulating actuator designed for precise control of dampers and valves in commercial HVAC systems. This electronic actuator provides proportional control with smooth, continuous modulation for accurate positioning throughout its full stroke range.

Key Features:

• 24 VAC/DC universal voltage operation for flexible installation
• Non-spring return design maintains position on power loss
• Modulating control with 2 to 10 VDC or 4 to 20 mA control signal
• Quick-connect wiring terminals for fast installation
• 90-degree rotation with adjustable stroke limiting
• Manual override for emergency positioning and commissioning
• Durable construction for long-term reliability in demanding environments
• Compact design suitable for tight installation spaces

Ideal for applications requiring proportional damper control in VAV systems, economizers, and other HVAC air handling applications. The non-spring return feature ensures the actuator holds its last position during power interruptions, making it suitable for applications where fail-in-place operation is preferred.
