Johnson Controls VG1845ANH923BGB 1/2 in 3-Way Ball Valve Assembly 11.7Cv 24V On/Off Spring Return

The Johnson Controls VG1845ANH923BGB is a factory-assembled 1/2 in. three-way ball valve and actuator assembly from the VG1000 Series, designed for precise flow control in commercial HVAC hydronic systems. This complete assembly pairs a forged brass valve body with stainless steel trim with a 24 VAC, two-position (on/off), spring-return electric actuator featuring high-temperature linkage and one built-in auxiliary switch.

Key Features:

• Valve Size: 1/2 in. NPT female threaded connections
• Configuration: 3-way mixing/diverting pattern
• Flow Coefficient: Cv = 11.7
• Actuator Voltage: 24 VAC
• Control Signal: Two-position (on/off)
• Fail-Safe Action: Spring return — counterclockwise (CCW); normally open
• Auxiliary Switch: One switch included
• High-Temperature Linkage: Included for elevated temperature applications
• Trim Material: Stainless steel ball and blowout-proof stem
• Body Material: Forged brass
• Seat Material: Graphite-reinforced PTFE with EPDM O-ring backing
• Flow Characteristic: Equal percentage on the in-line (coil) port; linear on the bypass port
• Leakage Rating: ANSI/FCI 70-2, Class IV (0.01% of Cv maximum, control port)
• Closeoff Pressure: 50 psid (three-way)
• Media: Hot water, chilled water, and up to 50% glycol solutions
• Fluid Temperature Range: 23°F to 203°F (-5°C to 95°C)
• Life Expectancy: 200,000 leak-free full cycles minimum

The VG1000 Series is engineered for long-term, maintenance-free operation in building automation and HVAC control applications. The specially designed PTFE seat reduces operating torque, enabling use of compact, energy-efficient actuators. The factory-mounted assembly with integral direct-coupling linkage simplifies installation and eliminates the need for separate linkage kits.
