Belimo G220S-J+LVKB24-SR 3/4" 2-Way Globe Valve Assembly 5.5 Cv Electronic Fail-Safe 24V Modulating

The Belimo G220S-J+LVKB24-SR is a pre-assembled 2-way globe valve and electronic fail-safe actuator combination designed for precise proportional control of hot water, chilled water, or steam in commercial HVAC systems. The 3/4" stainless steel trim valve body features female NPT connections and is rated to ANSI Class 250, with a flow coefficient (Cv) of 5.5.

The included LVKB24-SR actuator provides electronic fail-safe spring-return operation, powered by AC/DC 24V, and accepts a 2–10 VDC modulating control signal for accurate proportional positioning. In the event of a power loss, the actuator returns to its fail-safe position via spring return, ensuring system safety and process integrity.
