Description
The Johnson Controls VG7241ET is a 2-way, normally open globe valve engineered for precise flow control in commercial HVAC hydronic systems. Built with a cast bronze body and brass trim, this valve delivers long-lasting corrosion resistance and reliable performance in demanding heating and cooling applications.
Key Features
- 2-way, normally open (N.O.) configuration for fail-safe operation
- 1/2″ NPT end connections for straightforward installation in standard piping systems
- 1.8 Cv flow coefficient for accurate flow capacity sizing
- Equal percentage flow characteristic for precise, stable modulating control across the full valve stroke
- Cast bronze body with brass trim for superior durability and corrosion resistance
- Standard threaded stem design for compatibility with a wide range of Johnson Controls actuators
- Push-down-to-close (PDC) stem action for predictable, reliable valve response

Applications
The VG7241ET is ideal for modulating control of hot water, chilled water, and steam service in commercial HVAC systems. Its equal percentage flow characteristic makes it well-suited for applications requiring tight, stable control at low flow rates — such as fan coil units, air handling units, and terminal equipment. The normally open fail-safe position ensures continued flow in the event of actuator power loss, supporting system safety and occupant comfort.
Compatibility
Designed to pair with Johnson Controls VA, VB, and VE series electric actuators. The standard threaded stem and push-down-to-close action ensure broad actuator compatibility within the Johnson Controls valve and actuator product family.
