Johnson Controls VG1845AB+9A4GGA 3-Way 1/2" NPT Stainless Steel Ball Valve Assembly Cv 0.50

The Johnson Controls VG1845AB+9A4GGA is a 3-way stainless steel characterized control valve (CCV) assembly designed for precise flow regulation in hydronic heating and cooling systems. With a 1/2" NPT connection and a Cv flow coefficient of 0.50, this compact valve is engineered for low-flow HVAC applications requiring accurate modulating control.

The VG1845AB valve body features a stainless steel ball and stem construction for superior corrosion resistance and long-term durability in demanding building automation environments. The 3-way configuration allows for mixing or diverting service, making it well-suited for fan coil units, air handling units, and terminal equipment in commercial and light industrial HVAC systems.

Key Features:

• 3-Way Configuration: Suitable for mixing or diverting hydronic flow applications
• 1/2" NPT Connections: Standard threaded pipe connections for straightforward installation
• Stainless Steel Construction: Ball and stem in stainless steel for corrosion resistance and extended service life
• Cv 0.50 Flow Coefficient: Calibrated for precise low-flow control in small terminal HVAC equipment
• Characterized Ball Design: Provides equal-percentage flow characteristic for stable, linear control response
• Bundled Valve + Actuator Assembly: VG1845AB valve body paired with the 9A4GGA actuator for a ready-to-install solution
• Compatible with Johnson Controls Building Automation Systems: Designed for integration with Johnson Controls DDC and BAS controllers

The VG1845AB+9A4GGA assembly is an ideal drop-in solution for building automation system (BAS) upgrades and new construction projects where compact, reliable hydronic control is required. The pre-matched valve and actuator combination simplifies specification, procurement, and installation.
