Johnson Controls VG1845BN+923BUA 3/4" 3-Way Ball Valve Assembly with Spring Return Actuator, 11.7 Cv

The Johnson Controls VG1845BN+923BUA is a factory-assembled combination of a 3/4-inch, three-way forged brass ball valve and a VA9203-BUA spring return electric actuator, designed for precise on/off flow control in commercial and industrial HVAC applications. This pre-assembled unit delivers reliable regulation of chilled water, hot water, and 50% glycol solutions in building automation systems.

The VG1845BN valve features stainless steel ball and stem trim with female NPT threaded end connections and a characterized insert for equal percentage flow control. With a Cv rating of 11.7 and a closeoff pressure rating of 200 psig, it is engineered for high-performance duty in demanding hydronic systems. Maximum working water pressure is 580 psi, and the valve supports steam service up to 15 psig when used with a thermal spacer.

The 923BUA actuator is a spring return, 2-position (on/off) direct-coupled electric actuator operating across a wide universal voltage range of 85–264 VAC at 50/60 Hz, making it compatible with a broad range of control panel and power supply configurations. The spring return mechanism provides fail-safe operation, automatically returning the valve to its default position upon loss of power.
