Johnson Controls VG1845AN+923BGA 1/2 in. Three-Way Ball Valve Assembly with Spring-Return Actuator, 11.7 Cv, 24V, 2-Position

The Johnson Controls VG1845AN+923BGA is a factory-assembled, three-way ball valve and spring-return electric actuator package designed for precise flow control in commercial and industrial HVAC applications. The assembly pairs the VG1845AN 1/2 in. NPT stainless steel trim ball valve (Cv 11.7) with the VA9203-BGA-2 spring-return electric actuator, providing reliable two-position on/off control at 24 VAC/VDC.

Part of the Johnson Controls VG1000 Series, these ball valves are engineered to regulate the flow of chilled water, hot water, and 50% glycol solutions — as well as low-pressure steam (up to 15 psig at 250°F) in stainless steel trim configurations. The equal percentage flow characteristic and ANSI Class IV leakage rating (0.01% of Cv) ensure accurate and dependable modulation under varying load conditions.

The VA9203-BGA-2 actuator provides 27 lb-in of torque and features a mechanical spring-return system that automatically drives the valve to its fail-safe default position upon loss of power, improving system reliability and safety. The actuator mounts directly to the valve body with a single screw and includes a microprocessor-controlled brushless DC motor for smooth, consistent operation.
