Johnson Controls VG7241LT+3003E Valve Assembly

The Johnson Controls VG7241LT+3003E is a 3/4-inch, 2-way normally open pneumatic globe valve designed for modulating control of hot water, chilled water, and steam in commercial HVAC systems. This assembly features a rugged cast bronze body and brass trim, ensuring long-term durability in high-demand hydraulic circuits. Rated for a 7.3 Cv flow coefficient, the valve utilizes an equal percentage flow characteristic to provide precise linear heat output even during fluctuating pressure drops. Driven by a 3003E enclosed pneumatic actuator with a 3-inch effective diaphragm area, the unit operates on a 9-13 PSI spring range for reliable fail-safe positioning. Ideal for terminal unit and air handling applications, the NPT threaded connections allow for straightforward field installation. This Johnson Controls VG7000 series valve is engineered for high-temperature compatibility, supporting media temperatures up to 281°F, making it a versatile choice for steam and water-based climate control loops.

• Precise Flow Control: The 7.3 Cv equal percentage plug provides stable modulation and prevents hunting in modern building automation systems.
• Fail-Safe Operation: Normally open configuration ensures the valve returns to the open position upon loss of pilot air, protecting systems from freezing or stagnation.
• Industrial-Grade Build: Cast bronze body construction and brass internal trim minimize corrosion and extend the service life of the valve assembly.
• Flexible Compatibility: The 9-13 PSI spring range integrates seamlessly with standard pneumatic controllers and HVAC pneumatic actuators.

What is the maximum static pressure for the VG7241LT?
The VG7000 series bronze valves are typically rated for ANSI Class 250, supporting static pressures up to 400 psig at lower temperatures and 250 psig at 281°F.

Can this valve be used for steam applications?
Yes, this Johnson Controls pneumatic valve is suitable for saturated steam applications up to 35 psig when equipped with the appropriate hardware and trim.

What size air line connection is required for the actuator?
The enclosed 3003E pneumatic actuator typically features a 1/8-inch NPT air connection for standard pilot air lines.
