Johnson Controls VG7241PT+72CHGA Valve Assembly

The Johnson Controls VG7241PT+72CHGA is a high-performance 1 1/4" bronze globe valve assembly designed for precise modulation in commercial HVAC systems. This 2-way normally open valve features an 18.5 Cv flow coefficient and an equal percentage flow characteristic, making it ideal for regulating hot water, chilled water, or saturated steam. The rugged cast bronze body is paired with brass trim and an ANSI Class IV leakage rating, ensuring tight shut-off and long-term reliability in demanding hydronic circuits.

Driven by a 24Vac spring return actuator, the VG7241PT+72CHGA offers versatile control options, including 0(2)-10Vdc, 0(4)-20mA, two-position, or floating signals, all of which are field-selectable. This assembly serves as the official replacement for VG7241PT+926AGA and VG7241PT+926HGA, allowing for seamless integration into existing Johnson Controls VG7000 series installations. With a 400 psi static pressure rating and a temperature range of 35-284°F, it provides the robust performance required for modern building automation systems.

• Precise Modulation: The equal percentage flow design ensures stable control linear to the actuator stroke.
• Field Flexibility: Includes a multi-signal actuator that supports proportional, floating, or on/off control.
• Direct Retrofit: Engineered as the primary replacement for legacy VG7241PT models, reducing downtime during upgrades.
• Fail-Safe Security: Integrated spring return mechanism ensures the valve returns to its normally open position during power loss.
• High Temperature Capacity: Built to handle saturated steam up to 35 psig and water/glycol solutions up to 284°F.

Is the control signal fixed on this unit?

No, the VA7820 actuator used in this assembly features field-selectable switches, allowing you to choose between 0-10Vdc proportional, floating, or two-position control based on your controller's output.

Can this valve be used for steam applications?

Yes, the VG7241PT+72CHGA is rated for saturated steam up to 15 psig for brass trim configurations and up to 35 psig in specific water-to-steam transitions.

What is the close-off pressure rating?

This assembly provides a maximum close-off pressure of 111 psi, ensuring reliable operation against high differential pressures in 1 1/4" NPT piping systems.
