Belimo FGVL+RVB24-MFT Actuator

The Belimo FGVL+RVB24-MFT is a precision-engineered globe valve actuator assembly designed for demanding HVAC applications requiring high-torque modulation. This 24V non-spring return actuator is coupled with the FGVL globe valve linkage, providing a robust solution for controlling flow in chilled water, hot water, or low-pressure steam systems. Utilizing Multi-Function Technology (MFT), this unit allows for field-adjustable parameters including input signal, feedback signal, and running time, ensuring seamless integration with existing Building Automation Systems (BAS). The RVB24-MFT delivers consistent linear force to handle high differential pressures, maintaining precise control over valve stroke. For contractors, the universal power supply compatibility and the ability to configure the proportional control signal (2-10 VDC, 4-20 mA) make it a versatile cross-reference part for legacy globe valve retrofits. Built with a rugged NEMA 2 (IP54) housing, it withstands mechanical stress while maintaining signal accuracy across the entire travel range.

• Multi-Function Technology (MFT): Enables field customization of control signals and feedback for precise system tuning.
• High-Torque Performance: The RVB series provides the necessary force for high close-off pressure requirements in globe valve assemblies.
• Simplified Linkage: The FGVL linkage ensures a direct mechanical connection, reducing hysteresis and mechanical wear.
• Manual Override: Features a manual crank for emergency positioning and commissioning without power.
• Energy Efficiency: Low power consumption during holding cycles optimizes long-term operational costs for commercial facilities.

Common Questions

How do I calibrate the stroke for the FGVL+RVB24-MFT?
The actuator features an automatic stroke adaptation function. Once powered and connected to the linkage, initiating the calibration sequence allows the RVB24-MFT to detect the mechanical limits of the valve for 100% position accuracy.

Can this actuator be used for 3-point floating control?
Yes, due to its MFT property, the actuator can be configured for on/off, floating, or proportional control signals depending on the specific job site requirements.

Is the FGVL linkage compatible with non-Belimo valves?
The FGVL linkage is specifically engineered for Belimo and certain select globe valve bodies; always verify the valve stem diameter and bonnet dimensions before installation.
