Johnson Controls VG1845BN+9T4GGA 3/4 in. 3-Way Ball Valve Assembly with VA9104 Non-Spring Return Proportional Actuator

The Johnson Controls VG1845BN+9T4GGA is a factory-assembled 3-way, 3/4-inch NPT forged brass ball valve paired with a VA9104 Series non-spring return electric actuator, designed for precise proportional flow control in commercial and industrial HVAC systems. With a flow coefficient (Cv) of 11.7 on Port A and 5.8 on Port B, this assembly provides accurate regulation of hot water, chilled water, and 50/50 glycol solutions.

Part of the Johnson Controls VG1000 Series, this valve features a stainless steel ball and blowout-proof stem for long-term durability and tight shutoff, with a close-off pressure rating of 200 psig. The factory-mounted VA9104-GGA-3S actuator accepts a proportional 0–10 VDC control signal, making it compatible with a wide range of building automation system (BAS) controllers.

Key Features:

• Valve Size: 3/4 in. NPT threaded connection, 3-way configuration
• Flow Coefficient: Cv 11.7 (Port A / inline) and Cv 5.8 (Port B / bypass)
• Valve Body: Forged brass construction with stainless steel ball and blowout-proof stem
• Close-Off Pressure: 200 psig
• Flow Characteristic: Equal percentage on Port A (coil/inline); linear on Port B (bypass)
• Rangeability: 500:1 for accurate control under all load conditions
• Actuator Type: VA9104 Series — non-spring return, direct-mount electric actuator
• Running Torque: 35 lb-in (4 Nm)
• Control Signal: Proportional 0–10 VDC (24 VAC supply)
• Power Consumption: 2.9 VA
• Electrical Connection: M3 screw terminals
• Actuator Housing: NEMA 1, IP40
• Fluid Temperature Range: 23°F to 203°F (-5°C to 95°C)
• Actuator Ambient Temperature: -4°F to 140°F (-20°C to 60°C)
• Nominal Travel Time: 60 seconds at 60 Hz for 90° rotation
• Media: Hot water, chilled water, 50/50 glycol solution

The VG1845BN+9T4GGA is factory-assembled and ready for direct installation, reducing field labor time and ensuring proper actuator-to-valve alignment. The direct-coupled, non-spring return design holds its last position on power loss. Compatible with Johnson Controls Metasys and other BAS platforms that provide a 0–10 VDC proportional output signal.
