Johnson Controls VG7241PT+423AGA Valve Assembly

The Johnson Controls VG7241PT+423AGA is a professional-grade 2-way normally open globe valve assembly designed for high-performance fluid control in commercial HVACR systems. Built with a rugged 1 1/4-inch cast bronze body and brass trim, this assembly is engineered to regulate the flow of hot water, chilled water, or 15 psig saturated steam with a high-capacity 18.5 Cv rating. The equal percentage flow characteristic ensures precise modulation, critical for maintaining setpoint stability in hydronic heating and cooling loops. Powering this unit is the VA-4233-AGA-2 electronic actuator, which operates on 24VAC or 24VDC and provides reliable floating control. A robust 15-second spring return fail-safe mechanism ensures the valve returns to the stem-up (open) position during power loss, protecting equipment from potential temperature swings or stagnation. With its NPT female threaded connections, this direct-mount valve assembly simplifies field installation and provides a compact 61 lb-force close-off for demanding building automation systems.

• Precision Flow Control: Featuring an equal percentage flow plug, this valve delivers accurate linear temperature control across the full range of the controller’s signal.
• Reliable Fail-Safe: Integrated spring return actuator guarantees the valve fails to the open position, ensuring continued flow during electrical interruptions.
• Durable Construction: The cast bronze body and brass trim are built to withstand temperatures ranging from 35°F to 250°F, ideal for diverse HVAC valve applications.
• Streamlined Installation: Designed for direct-mount connectivity, eliminating the need for external linkages and reducing potential failure points in the field.
• High Close-Off: Provides a 38 psi close-off rating, suitable for 1-1/4 inch NPT commercial piping systems.

What is the fail-safe position of this assembly?
The VG7241PT+423AGA is a normally open valve. In the event of a power failure, the spring return mechanism automatically drives the valve stem up to the open position.

Can this valve be used for steam applications?
Yes, this brass trim globe valve is rated for 15 psig saturated steam, making it a versatile choice for steam-based heating systems as well as chilled water loops.

What type of control signal is required?
This model utilizes a 24Vac/Vdc floating control signal, making it compatible with most standard 3-wire incremental controllers in modern building management systems.
