Johnson Controls VG1845ANH923BGA 1/2" 3-Way Ball Valve Assembly 11.7 Cv Spring Return 24V On/Off

The Johnson Controls VG1845ANH923BGA is a factory-assembled, 3-way electric ball valve assembly from the VG1000 Series, designed for precise flow control in commercial HVAC hydronic systems. The assembly pairs a 1/2-inch NPT stainless steel trimmed ball valve (Cv = 11.7/5.8) with a direct-coupled spring return electric actuator and high-temperature linkage, offering reliable on/off control at 24 VAC.

Key Features:

• Valve Body: Forged brass construction with stainless steel ball and blowout-proof stem for long-term durability
• Flow Capacity: Cv = 11.7 (Port A) / 5.8 (Port B) with equal percentage flow characteristic on the inline port
• Connection: 1/2-inch female NPT threaded connections
• Body Pattern: 3-way mixing or diverting configuration
• Actuator: Spring return, counterclockwise, Port A (coil) open on spring — 24 VAC, on/off control, no auxiliary switch
• High-Temperature Linkage: Included for elevated fluid temperature applications
• Closeoff Pressure: 200 psig for 1/2-inch 3-way configuration
• Fluid Temperature Range: 23°F to 203°F (-5°C to 95°C)
• Media Compatibility: Hot water, chilled water, and up to 50/50 glycol solution for HVAC systems
• Seat Material: Graphite-reinforced PTFE seats with dual EPDM stem seals for leak-free operation
• Leakage Rating: ANSI Class IV (0.01% of Cv) on control port
• Cycle Life: Rated for 200,000 leak-free full stroke cycles
• Compliance: UL Listed, CSA Certified, CE Mark

The VG1000 Series valve assemblies are engineered for use in commercial heating, ventilation, and air conditioning systems where dependable, compact, and maintenance-free hydronic control is required. The factory-mounted actuator eliminates field assembly complexity and ensures consistent performance right out of the box.
