Johnson Controls VG1245BN+923GGB Two-Way Stainless Steel Ball Valve with Spring-Return Actuator - 3/4

The Johnson Controls VG1245BN+923GGB is a factory-assembled ball valve and actuator assembly designed for precise control of hot water, chilled water, and 50% glycol solutions in commercial HVAC systems. This combination unit features a 3/4" NPT two-way ball valve with stainless steel trim paired with a VA9203-GGB-2Z proportional electric spring-return actuator.

VG1245BN Ball Valve Features:

• 3/4" female NPT threaded connections for easy installation
• Flow coefficient (Cv) of 11.7 for optimal flow capacity
• Stainless steel trim construction for durability and corrosion resistance
• Two-way design for on/off or modulating control applications
• Maximum working pressure: 580 PSI water, 15 PSI steam (with thermal spacer)
• Closeoff pressure rating of 200 PSI
• Maximum water temperature: 284°F (140°C)
• Compatible with VG1000 Series valve systems

VA9203-GGB-2Z Actuator Specifications:

• 24V AC/DC proportional control with 0-10 VDC input signal
• Spring-return operation provides fail-safe positioning (spring open configuration)
• 27 lb-in (3 N-m) torque output for reliable valve operation
• 90-second cycle time for full 90-degree rotation
• One SPDT auxiliary switch (Model 923GGB switch configuration)
• Direct-mount design eliminates external linkages
• Operating temperature range: up to 140°F ambient
• Power consumption: 5.1 VA
• Integral 1/2" threaded conduit connector for field wiring

This pre-assembled valve and actuator combination is ideal for use in heating, ventilating, and air conditioning systems where proportional control is required. The spring-return actuator ensures the valve returns to the open position upon power loss, providing fail-safe operation for critical applications. Factory assembly ensures proper alignment and commissioning, reducing installation time and potential errors.
