Johnson Controls VG7243LT+423BGA Valve Assembly

Upgrade your hydrant or terminal unit control systems with the Johnson Controls VG7243LT+423BGA Valve Assembly. This 3/4-inch normally open globe valve is engineered for high-demand HVACR applications, featuring a 7.3 Cv equal percentage flow characteristic for precise modulation of hot water, chilled water, or 15 psig saturated steam. Built with a rugged cast bronze body and stainless steel trim, this assembly ensures long-term resistance to corrosion and wear in aggressive media environments. The integrated VA-4233-BGA series actuator provides a reliable 61 lb-in torque output and a spring return fail-safe mechanism that drives the valve to the stem-up position during power loss. Operating on 24VAC/VDC power, this direct-mount on-off valve assembly eliminates the need for complex linkages, simplifying field installation and ensuring a tight shut-off against high differential pressures. Trust this veteran-grade HVAC control valve for consistent performance in light industrial and commercial building automation systems.

• Enhanced Durability: Features stainless steel trim and a 250 psi static pressure rating for extended service life in steam and water systems.
• Reliable Fail-Safe: The spring return actuator ensures a normally open default position (stem up) to prevent system freeze-ups or stagnation during power failure.
• Precision Control: An equal percentage flow curve allows for stable and accurate heat transfer regulation across varying load conditions.
• Contractor Friendly: The 3/4" NPT connection and direct-mount design allow for rapid swap-outs without the hassle of separate mounting kits.

Is this valve compatible with 24V DC systems?
Yes, the VA-4233-BGA electric actuator is designed to operate on either 24 VAC or 24 VDC power sources, providing flexibility for different control panels.

What is the maximum fluid temperature this assembly can handle?
The VG7000 series bronze valve is rated for fluid temperatures ranging from 35°F to 250°F, making it suitable for both chilled water and low-pressure steam applications.

Can I use this for modulating (0-10V) control?
No, this specific model is a two-position on-off actuator. For proportional modulation, a different actuator series in the Johnson Controls lineup would be required.
