Johnson Controls VG1845AN+923BUA 1/2 in 3-Way Ball Valve with Spring Return Actuator 11.7 Cv

The Johnson Controls VG1845AN+923BUA is a factory-assembled 1/2 in. three-way forged brass ball valve paired with a VA9203-BUA-2 series spring-return electric actuator. This pre-assembled combination is engineered for precise on/off flow control of hot water, chilled water, or 50% glycol solutions in commercial and industrial HVAC systems.

The VG1845AN valve body belongs to the VG1000 Series and features a 1/2 in. female NPT connection, a three-way configuration with a flow coefficient (Cv) of 11.7, and an equal percentage flow characteristic. The forged brass body with stainless steel trim delivers an ANSI Class IV leakage rating of 0.01% of maximum Cv and a service life of 200,000 leak-free cycles.

The factory-mounted VA9203-BUA-2 actuator is a direct-coupled, spring-return electric actuator providing reliable two-position (on/off) control. In the event of a power loss, the mechanical spring return automatically drives the valve to its fail-safe position. The actuator operates over a wide supply voltage range of 85 to 264 VAC at 50/60 Hz, making it compatible with a broad range of electrical systems without additional transformers.
