Johnson Controls VG1245BN+9A4GGA 3/4" Two-Way Proportional Control Valve with Actuator

The Johnson Controls VG1245BN+9A4GGA is a professional-grade motorized control valve assembly designed for precise modulating control in commercial HVAC hydronic systems. This package combines a VG1245BN two-way brass globe valve body with a 9A4GGA proportional electronic actuator for accurate flow regulation in heating and cooling applications.

Valve Body Specifications:

• 3/4 inch NPT threaded connections for easy installation
• Two-way globe valve design for on/off or modulating control
• Flow coefficient (Cv) of 11.7 for optimal flow capacity
• Durable brass construction for corrosion resistance and longevity
• Normally seated return (NSR) spring return configuration

Actuator Features:

• 24V AC/DC proportional electronic actuator
• Modulating control for precise temperature regulation
• Direct-coupled mounting for compact installation
• Reliable spring return mechanism for fail-safe operation

This valve assembly is ideal for use in chilled water systems, hot water heating loops, fan coil units, unit heaters, and other commercial HVAC applications requiring accurate flow control. The proportional actuator allows for seamless integration with building automation systems and DDC controllers for optimal energy efficiency and comfort control.
