Johnson Controls VG1845BN+9A4GGA 3/4" 3-Way Forged Brass Ball Valve Assembly with Non-Spring Return Proportional Actuator

The Johnson Controls VG1845BN+9A4GGA is a factory-assembled 3/4-inch, three-way forged brass ball valve paired with a VA9104-series non-spring return electric actuator. Part of the VG1000 Series, this valve and actuator combination is engineered to regulate the flow of hot water, chilled water, 50% glycol solutions, and low-pressure steam (up to 15 psig) in commercial HVAC systems.

The valve body features a forged brass construction with a stainless steel ball and blowout-proof stem, providing exceptional durability and corrosion resistance. The included VA9104-xGA-2S actuator operates on 24 VAC/DC with proportional control via a DC 0–10 V or 0–10 mA input signal, enabling precise modulating control in response to a building automation controller. A 120-inch (10-foot) plenum-rated cable is included for flexible wiring runs.

Key Features:

• 3/4" NPT (Female) threaded end connections for straightforward installation into standard piping systems
• Cv rating of 11.7 for accurate flow control across a wide range of load conditions
• Forged brass body with 580 psig static pressure rating and 200 psig closeoff pressure rating for reliable shutoff
• Stainless steel ball and blowout-proof stem for long service life in both hot and chilled water applications
• 500:1 rangeability with a characterized insert for equal-percentage flow control, providing accurate control under all load conditions
• Graphite-reinforced PTFE seats (15% graphite) for enhanced wear resistance and sealing
• Non-spring return, proportional actuator — VA9104-xGA-2S, 24 VAC/DC, DC 0(2)–10 V or 0(4)–20 mA input signal
• 35 lb-in. torque output from direct-mount electric actuator
• Fluid temperature range: -22°F to 284°F (-30°C to 140°C) for water; 15 psig saturated steam with thermal barrier
• 120-inch (10 ft) plenum-rated cable with 19 AWG conductors included
• Compatible with Johnson Controls M9000 and VA9000 Series actuators for future retrofit flexibility

This factory-assembled valve and actuator combination simplifies procurement and ensures compatibility between the VG1845BN valve body and the 9A4GGA proportional actuator. It is ideal for VAV systems, fan coil units, air handling units, and other commercial HVAC hydronic applications requiring precise proportional flow control.
