Johnson Controls VG7243NT+71CHGC 1" NPT 11.6Cv Proportional Globe Valve with 24V Non-Spring-Return Actuator

The Johnson Controls VG7243NT+71CHGC is a factory-assembled combination valve and actuator package designed for precise proportional control of hot water, chilled water, and steam hydronic systems in commercial HVAC applications. The assembly pairs a 1" NPT bronze two-way globe valve body rated at 11.6 Cv with a 24V proportional, non-spring-return (NSR) actuator featuring an integrated auxiliary switch.

Key Features:

• Valve Body (VG7243NT): 1" NPT end connections, 11.6 Cv flow coefficient, two-way normally open configuration, bronze body construction for durability and corrosion resistance
• Actuator (71CHGC): 24V AC/DC proportional control signal, non-spring-return operation, auxiliary (AUX) switch for end-of-travel position feedback and interlock applications
• Proportional (modulating) control for accurate flow regulation in response to a 0–10V or 4–20mA control signal
• Non-spring-return design retains valve position on power loss — ideal where fail-in-place operation is required
• Factory-matched valve and actuator assembly ensures optimized performance and simplified installation
• Compatible with Johnson Controls and other major building automation and direct digital control (DDC) systems
• Suitable for HVAC hydronic heating and cooling coil applications in commercial buildings

The VG7243NT+71CHGC is part of Johnson Controls' proven VG7000 globe valve series, widely used in building automation systems for terminal unit control, air handling units, and fan coil units. The included auxiliary switch provides a dry contact output useful for system status monitoring, BAS integration, or interlock wiring.
