Belimo UGVL+LVKX24-3 Actuator

The Belimo UGVL+LVKX24-3 is a high-performance globe valve linkage and actuator assembly designed for precise fluid control in demanding HVACR applications. This field-mountable solution combines a linear valve actuator with 112 lbf of force, ensuring reliable operation under high static pressures. Operating on a 24VAC/DC power supply, it utilizes a floating point control signal to provide accurate positioning for pressure-independent or standard globe valve bodies. A critical feature of the LVKX24-3 series is the electronic fail-safe mechanism, which uses integrated capacitors to drive the valve to a predetermined safety position during power loss, preventing system damage or overflow. The UGVL linkage simplifies retrofitting or new installations, providing a robust mechanical connection that maintains alignment and reduces stem wear. Engineered for professional contractors requiring durable Belimo valve actuators, this unit supports efficient thermal management in commercial air handling units and hydronic loops.

Key Benefits

• Electronic Fail-Safe Operation: Provides a dependable safety return to the home position using capacitor energy storage without the mechanical overhead of traditional springs.
• High Linear Force: Delivers 112 lbf (500 N) of force, making it compatible with a wide range of globe valve sizes for tight shut-off performance.
• Universal Compatibility: The UGVL globe valve linkage allows for seamless integration with varied valve bodies, streamlining field replacements.
• Flexible Power Requirements: Operates efficiently on both 24V AC and DC, reducing inventory requirements for different site voltages.
• Floating Point Control: Ensures stable and incremental adjustments for precise temperature and flow regulation in hydronic systems.

Common Questions

How does the electronic fail-safe differ from a mechanical spring return?
The LVKX24-3 utilizes internal capacitors rather than a mechanical spring, allowing for a more compact design and customizable fail-safe direction (Normally Open or Normally Closed) via a switch.

Can this actuator be installed on other manufacturers' globe valves?
The Belimo UGVL linkage is specifically designed to adapt Belimo actuators to various valve bodies; however, stem height and thread pitch must be verified for total compatibility.

What is the maximum stroke length for this linkage assembly?
The assembly is optimized for globe valves with a standard stroke length, typically up to 0.6 inches (15mm), ensuring full travel and positive closure.
