Johnson Controls VG1845BN+923BGB 3/4 in. Three-Way Ball Valve Assembly with 24V Spring Return Actuator Cv 11.7

The Johnson Controls VG1845BN+923BGB is a factory-assembled, 3/4 in. three-way forged brass ball valve with stainless steel trim, paired with a VA9203-BGB series 24V AC spring return electric actuator for two-position (on/off) control. Designed for commercial and industrial HVAC applications, this valve assembly delivers precise flow regulation with the reliability of Johnson Controls' VG1000 Series platform.

Key Features:

• Connection Size: 3/4 in. female NPT (FNPT)
• Valve Configuration: Three-way body pattern with characterized insert for equal percentage flow control
• Flow Coefficient (Cv): 11.7 (Port A) / 7.41 (Port B)
• Trim Material: Stainless steel
• Closeoff Pressure: 200 psi
• Max Working Water Pressure: 580 psi
• Max Water Temperature: 284°F (140°C)
• Steam Rating: 15 psig with optional M9000-561 thermal barrier (thermal spacer required)
• Actuator Voltage: 24V AC
• Actuator Control Type: Two-position (on/off), spring return
• Spring Return: Mechanical spring return provides rated torque with or without power applied
• Compatible Fluids: Chilled water, hot water, 50% glycol solutions, and low-pressure steam

The VG1000 Series ball valve body features a characterized insert for equal percentage flow characteristics at the in-line (coil) port and linear flow characteristics at the bypass port, making it well-suited for heating and cooling coil bypass applications. The direct-coupled VA9203-BGB spring return actuator mounts directly to the valve body without the need for additional linkage hardware, simplifying installation and reducing potential failure points.

This assembly is compatible with Johnson Controls M9000 and VA9000 series actuator accessories and is suitable for use in conjunction with a building automation system (BAS) controller for reliable on/off zone or terminal unit control.
