Johnson Controls VG7241ST Valve

The Johnson Controls VG7241ST is a heavy-duty 2-inch NPT globe valve engineered for high-demand HVAC control systems. This 2-way normally open valve features a robust cast bronze body and brass trim, providing a reliable 46.2 Cv rating with an equal percentage flow characteristic for precise modulation of hot water, chilled water, or 35 psig saturated steam. Designed for a push-down-to-close action, it utilizes a standard threaded stem compatible with various pneumatic and electric actuators, including the VA-7000 and M9000 series. Its ANSI Class 250 rating ensures it stands up to high-pressure commercial environments, while the spring-loaded PTFE V-ring packing or equivalent elastomer disc seats minimize leakage. Whether you are managing domestic water or complex steam-fed coils, this 2" globe valve delivers the flow control accuracy required by modern building automation controllers. It serves as a direct replacement or core component for VG7000 Series valve assemblies, simplifying field installations for mechanical contractors.

Key Benefits

• Optimized Flow Control: Featuring a 46.2 Cv rating and equal percentage response, this valve provides linear heat output for superior temperature stability.
• Durable Construction: The cast bronze body and brass trim offer exceptional corrosion resistance in water and low-pressure steam applications.
• Versatile Actuation: Standard threaded stem design allows for seamless integration with pneumatic (MP8000/V-3000) or electric (VA-7000) actuators.
• High Pressure Resilience: Built to ANSI Class 250 standards, capable of handling water temperatures up to 281°F and maximum static pressures essential for commercial HVAC loops.

Common Questions

What is the fail-safe position for the VG7241ST?
This specific model is a normally open valve. Without an actuator or with a spring-return "stem-up" actuator, the valve remains in the open position to allow full flow.

Is this valve suitable for steam applications?
Yes, it is rated for saturated steam up to 35 psig when paired with a compatible high-temperature actuator and appropriate trim selection.

What actuators are compatible with this 2-inch valve?
The VG7241ST interfaces with Johnson Controls VA-715x, VA-720x, and VA-4233 electric actuators, as well as MP82 and V-3000 pneumatic actuators.
