Belimo G220S-K+LVB24-SR 3/4" 2-Way Globe Valve 7.5 Cv Non-Spring Return 24V Modulating Actuator

The Belimo G220S-K+LVB24-SR is a factory-assembled 2-way threaded globe valve and modulating actuator combination designed for precise proportional control in commercial HVAC applications. The G220S-K valve features a 3/4" connection, a flow coefficient (Cv) of 7.5, and stainless steel trim, rated to ANSI Class 250 for reliable performance in hot water, chilled water, and steam systems.

The included LVB24-SR actuator is a non-spring return (NSR), linear, modulating actuator operating on AC/DC 24V power. It accepts a DC 2–10V or 4–20mA proportional control signal for accurate flow modulation. A 500Ω resistor (accessory ZG-R01) can be used to convert a 4–20mA signal to 2–10V. The actuator requires only 2VA of transformer capacity (Class 2 power source), making it efficient and easy to integrate into building automation systems.
