Johnson Controls VG1245AEH923GGB NPT Ball Valve with Electric Actuator - 1/2 VA9203-GGB-2Z

The Johnson Controls VG1245AEH923GGB is a complete motorized ball valve assembly featuring a 1/2-inch NPT two-way stainless steel trim ball valve paired with a VA9203-GGB-2Z spring-return electric actuator. This valve assembly is designed for proportional control applications in commercial HVAC systems, providing precise modulation of hot water, chilled water, and glycol solutions.

Key Specifications:

• Valve Size: 1/2-inch NPT threaded connections
• Flow Coefficient (Cv): 1.9
• Configuration: Two-way ball valve with stainless steel trim
• Actuator Voltage: 24 VAC
• Actuator Type: Spring-return with thermal barrier and open spring-return mechanism
• Control Mode: Proportional modulating control
• Auxiliary Switches: One auxiliary switch for position indication
• Thermal Barrier: Model VA9203-GGB-2Z features integrated thermal protection

Features and Benefits:

• Stainless steel trim construction ensures long service life and corrosion resistance
• Spring-return actuator provides fail-safe positioning during power loss
• Proportional control enables precise temperature and flow regulation
• Thermal barrier protects actuator electronics in high-temperature applications
• Compact direct-mount design simplifies installation and reduces footprint
• Auxiliary switch provides position feedback for building automation systems

This valve assembly is ideal for zone control, heating and cooling coil applications, and general HVAC water distribution systems where reliable, proportional control with fail-safe operation is required. The spring-return mechanism automatically drives the valve to a predetermined safe position when power is interrupted, ensuring system safety and preventing damage.
