VG12A5JU+92NBAA Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG12A5JU+92NBAA is a factory-assembled high-performance valve and actuator combination designed to regulate the flow of hot water, chilled water, and 50/50 glycol solutions in commercial HVAC systems. This assembly couples a 4-inch, 2-way VG1000 Series flanged ball valve with an M9220-BAA-3 spring-return electric actuator. The system provides reliable ON/OFF two-position control with a 117 CV capacity, operating on a standard 120 VAC power supply. The assembly is engineered to ensure tight shutoff, exceptional flow control, and durable long-term performance under demanding environmental conditions.

Features

• High-torque M9220-BAA-3 spring-return electric actuator provides 177 lb-in of running and spring torque without needing complex damper linkages.
• 300 Series stainless steel ball and stem assembly enables use with high-temperature fluids and protects against corrosion.
• Amodel flow characterizing disk delivers an equal percentage flow characteristic for stable and accurate temperature control.
• EPDM double O-ring stem seal delivers tested leak-free operation up to 200,000 cycles.
• Spring-return safety mechanism automatically positions the valve to Spring OPEN upon power loss to prevent system overheating or freezing.
• Direct-mount design with reversible mounting orientation simplifies installation and saves field labor time.
