Belimo FGVL+AVKB24-3 Valve

The Belimo FGVL+AVKB24-3 is a high-performance retrofit globe valve linkage solution designed for seamless integration with flanged globe valves in demanding HVACR environments. This assembly features an AVKB24-3 24V actuator providing 450 lbf [2000 N] of force, ensuring reliable close-off against high differential pressures in chilled water, hot water, and steam applications. Engineered for flexibility, the universal flanged globe valve linkage supports both on/off and floating point control via a 24V AC/DC power supply. The integrated electronic fail-safe technology allows contractors to select the emergency return position (Normally Open or Normally Closed) via a field-selectable switch, providing critical protection during power loss. With a 90-second motor run time and a rugged NEMA 2 / IP54 rated enclosure, this Belimo valve actuator assembly is built for long-term operational stability. The 1.25-inch [32 mm] stroke capacity and included 5 mm hex manual override ensure the FGVL+AVKB24-3 meets technical requirements for precise fluid control in complex builds.

• Universal Compatibility: Specifically designed for retrofit flanged globe valve applications, fitting most major manufacturers' valve bodies.
• Electronic Fail-Safe: Integrated capacitance-driven fail-safe operation ensures the valve returns to its safety position in under 35 seconds.
• High Force Output: Delivers a consistent 450 lbf [2000 N] of linear force to maintain tight seal and prevent leakage under high close-off pressure.
• Precision Control: Supports 24V floating point control and on/off signals, allowing for stable integration with building automation systems.
• Durable Construction: Features a cast aluminum linkage and an 18 GA plenum-rated cable for superior environmental resistance.

• Can this unit be used for steam applications? Yes, the Belimo FGVL+AVKB24-3 is suitable for both water and steam, provided the fluid temperatures remain within the manufacturer's valve body specifications.
• How do I change the fail-safe direction? The fail-safe direction is easily reversible via a built-in switch on the actuator housing, allowing for field-adjustable Normally Open or Normally Closed logic.
• Is manual operation possible? Yes, the unit is supplied with a 5 mm hex crank (3/16" Allen) for manual override during commissioning or power failures.
