Johnson Controls VG1845BNH923BUA 3/4 in. 3-Way Stainless Steel NPT Ball Valve with Spring-Return Actuator 11.7 Cv

The Johnson Controls VG1845BNH923BUA is a factory-assembled, 3/4-inch, three-way ball valve from the VG1000 Series, paired with a spring-return electric actuator. Featuring stainless steel trim and NPT threaded end connections, this combination valve and actuator is engineered for reliable flow control in commercial and industrial HVAC hydronic systems, including heating and cooling coil applications.

The valve body offers a flow coefficient (Cv) of 11.7, providing precise fluid management under varied load conditions. The integrated VA9208-series spring-return actuator accepts a universal voltage input of 85–264V AC, making it compatible with a wide range of control panel configurations without the need for voltage-specific wiring. On loss of power, the actuator spring-returns to its fail-safe position with Port A open (counterclockwise spring return), ensuring safe system default behavior.

Key Features:

• Valve Size: 3/4 inch (DN20), three-way configuration
• Flow Coefficient (Cv): 11.7
• End Connections: NPT threaded
• Trim Material: Stainless steel
• Actuator Type: Spring-return electric (VA9208 Series)
• Control Signal: 2-position (On/Off)
• Supply Voltage: Universal 85–264V AC
• Fail-Safe Action: Spring return, Port A open (counterclockwise)
• Factory-Assembled: Valve and actuator pre-mounted for faster installation
• No Auxiliary Switches included

The VG1845BNH923BUA is designed for straightforward integration into building automation systems (BAS), reducing field installation time. The universal voltage input of the actuator simplifies replacement and retrofit projects across diverse electrical environments. This valve is ideal for diverting or mixing service in hydronic HVAC piping systems.
