Johnson Controls VG7441LT+423GGC 3/4" NPT Proportional Ball Valve with Spring Return Actuator

The Johnson Controls VG7441LT+423GGC is a complete electronic proportional ball valve assembly designed for precise modulating control in HVAC and building automation systems. This factory-assembled unit combines the VG7441LT valve body with the 423GGC spring return actuator for reliable, fail-safe operation.

Key Specifications:

• Connection Size: 3/4 inch NPT threaded connections
• Flow Coefficient (Cv): 7.3 for optimized flow capacity
• Actuator Type: 423GGC proportional spring return with auxiliary switches
• Operating Voltage: 24 VAC/VDC for integration with standard control systems
• Control Type: Proportional modulating control for precise flow regulation
• Fail-Safe Mode: Spring return to normally closed position on power loss
• Auxiliary Switches: Built-in position indication contacts

This proportional valve assembly provides accurate, continuously modulating control of water and glycol solutions in heating, cooling, and energy recovery applications. The spring return feature ensures the valve automatically closes during power interruptions or system failures, making it ideal for critical safety applications. The integrated auxiliary switches provide position feedback for building automation systems.
