Johnson Controls VG7241LT+3008E Valve Assembly
The Johnson Controls VG7241LT+3008E is a professional-grade bronze globe valve assembly engineered for precise flow regulation in demanding HVACR applications. This 2-way, normally open control valve features a 3/4-inch NPT connection and is designed to manage hot water, chilled water, and saturated steam up to 15 psi. Utilizing a 7.3 Cv equal percentage flow characteristic, this assembly ensures stable modulating control even under fluctuating system pressures, making it an ideal choice for air handling unit (AHU) and terminal unit applications.
The integrated V-3000-8001 pneumatic actuator (referenced by the 3008E code) provides a reliable 9-13 psi spring range for fail-safe operation. Built with a cast bronze body and durable brass trim, the VG7000 series assembly is rated for ANSI Class 250 service, ensuring long-term seat integrity and resistance to common system debris. Contractors appreciate the spring return pneumatic actuator design for its high close-off pressure ratings and the exposed yoke that allows for easy maintenance and visual stroke verification in the field.
Key Benefits for the Contractor:
- Optimized Flow Control: The equal percentage flow characteristic prevents hunting in the control loop, providing superior comfort and energy efficiency.
- Broad Media Compatibility: Rated for water, glycol solutions, and low-pressure steam service, reducing the need for multiple valve types on the job site.
- Robust Construction: Features a high-quality cast bronze body and brass trim for maximum durability and corrosion resistance.
- Reliable Fail-Safe: The spring return mechanism ensures the valve returns to the open position during a loss of pneumatic pressure, protecting sensitive coils and equipment.
- Simplified Maintenance: The standard Johnson Controls ring pack and threaded stem design allow for in-place repacking and easy actuator field swaps.
Common Questions Regarding the VG7241LT+3008E:
What is the maximum fluid temperature for this valve?
This 3/4 inch NPT valve is designed to handle fluid temperatures ranging from 35°F to 248°F (2°C to 120°C). For applications involving saturated steam, it is rated up to 15 psi.
Which pneumatic controllers are compatible with the 9-13 psi spring range?
The assembly is compatible with standard 3–15 psi pneumatic controllers. Use an 8 psi or 10 psi start point depending on your specific sequencing requirements for normally open operation.
Can this valve be mounted in any orientation?
It is best practice to mount the VG7000 series in an upright, vertical position. While horizontal mounting is possible, always ensure the actuator is not positioned below the valve body to prevent moisture damage from condensation.
