Johnson Controls VG7241LT+423BGA Valve Assembly

The Johnson Controls VG7241LT+423BGA is a heavy-duty 2-way normally open globe valve assembly designed for precise flow control in demanding HVACR applications. Built with a 3/4 inch NPT female threaded connection, this unit features a cast bronze body with brass trim, ensuring high-pressure integrity for hot water, chilled water, and 50/50 glycol solutions. The assembly is powered by a high-torque VA-4233 spring return electric actuator, providing reliable two-position control with a 7.3 Cv equal percentage flow characteristic to maintain stable temperature regulation across the coil.

Engineered for professional contractors, this VG7000 Series bronze valve offers a normally open (push-down-to-close) fail-safe position, ensuring the valve remains open upon loss of power to prevent system freezing or flow interruption. The integrated 24Vac/Vdc actuator delivers a consistent 61 in-lb torque and is rated for a close-off pressure of 132 psi. With its ANSI Class IV leakage rating and ability to handle fluid temperatures up to 250°F, this assembly provides the durability required for long-term service in commercial boiler and chiller loops.

• Optimized Control: The 7.3 Cv equal percentage flow ensures linear heat transfer and prevents hunting in modern DDC systems.
• Fail-Safe Protection: Reliable spring return failsafe mechanism automatically drives the valve to the normally open position during power loss.
• Rugged Construction: Features a corrosion-resistant cast bronze body and a stainless steel stem for extended life in saturated steam and water applications.
• Ease of Installation: Standard 3/4" FNPT connections and a pre-mounted VA-4233 actuator reduce site labor and configuration errors.

What is the maximum fluid temperature this valve can handle?
The VG7241LT valve body is rated for a maximum fluid temperature of 250°F (121°C), making it suitable for low-pressure steam and high-temperature hot water systems.

Can I use this assembly with a 24VDC power supply?
Yes, the 423BGA actuator is compatible with both 24Vac and 24Vdc power inputs for two-position (on/off) operation.

Is the actuator field-replaceable?
The VG7000 Series utilizes a standardized bonnet and stem design, allowing for the easy field retrofit or replacement of Johnson Controls actuators without removing the valve body from the piping.
