Belimo BGVL+LVKX24-MFT Actuator

The Belimo BGVL+LVKX24-MFT combines a high-performance butterfly valve linkage with a Multi-Function Technology (MFT) electronic fail-safe actuator. Designed for demanding HVAC applications, this assembly provides precise proportional control for chilled water, hot water, or steam systems. The LVKX24-MFT actuator operates on a 24V AC/DC supply and delivers consistent torque to manage high differential pressures without compromising shut-off integrity. Utilizing supercapacitor technology, the fail-safe function ensures the valve returns to its designated position during power loss, offering a reliable alternative to traditional mechanical spring returns. This HVAC valve actuator is fully programmable, allowing technicians to field-adjust parameters such as control signal, running time, and feedback configuration via the Belimo PC-Tool or handheld ZTH US. Its rugged construction ensures long-term linear globe valve performance in critical commercial HVAC automation environments. Installation is streamlined by the universal linkage, which simplifies the retrofitting process for existing valve bodies.

• Electronic Fail-Safe: Uses maintenance-free capacitors to provide reliable emergency positioning without the bulk of mechanical springs.
• MFT Programming: Allows for custom input/output signals (2-10 VDC, 4-20 mA) and adjustable run times for system optimization.
• High Close-off Pressure: Engineered to maintain tight shut-off even in high-flow hydronic pumping systems.
• Brushless DC Motor: Provides precise positioning and lower power consumption while improving overall component lifespan.
• Manual Override: Features an external button to allow manual positioning during commissioning or power failures.

Common Questions

How do I configure the control signal on the LVKX24-MFT?
The Belimo BGVL+LVKX24-MFT uses Multi-Function Technology, which requires a Belimo ZTH US tool or PC-Tool software to change factory default settings for proportional control signal and feedback.

Can this actuator be used in steam applications?
Yes, when paired with the appropriate BGVL linkage and valve body rated for steam service, this actuator is suitable for high-temperature fluid control common in HVACR systems.

What is the benefit of an electronic fail-safe vs. a spring return?
Electronic fail-safe actuators like this model offer more flexible control options, consistent timing during failure modes, and are generally more compact, making them ideal for retrofitting globe valves in tight mechanical spaces.
