Johnson Controls VG7241ST+71CHGA Valve Assembly

The Johnson Controls VG7241ST+71CHGA is a heavy-duty, 2-inch NPT globe valve assembly specifically engineered for regulating the flow of hot water, chilled water, and 50% glycol solutions in high-demand HVAC systems. This 2-way normally open valve features a robust cast bronze body and reliable brass trim, providing a high 46.2 Cv flow capacity with an equal percentage flow characteristic for precise linear temperature control. The assembly is powered by the VA7810-HGA-2 non-spring return electric actuator, which offers extreme versatility for field technicians. It supports 24Vac input and is field-selectable for proportional control (0-10 VDC or 4-20 mA), floating, or two-position signals, making it an ideal choice for complex building automation retrofits.

As a veteran's choice for durability, this assembly meets ASME B16.15 Class 250 standards and is rated for saturated steam up to 35 psig. The non-spring return design ensures the valve maintains its last position upon loss of signal, providing stability in stabilized loops. This model serves as the direct technical replacement for VG7241ST+7202G and VG7241ST+916GGA, maintaining the same 46 psi close-off pressure and NPT connection geometry to ensure a seamless drop-in installation for maintenance contractors.

• Universal Controller Compatibility: The VA7810 actuator supports 0(2)-10 VDC, 0(4)-20 mA, and floating inputs, reducing the need to carry multiple specialized valve stocks.
• High Flow Efficiency: The 46.2 Cv rating combined with equal percentage flow ensures tight control at low demand while maintaining high volume capacity.
• Industrial Build Quality: Built with a cast bronze body and long-life replaceable ring packing to ensure tight shutoff and extended service life in commercial piping.
• Direct Cross-Reference: Engineered as a verified replacement for older Johnson Controls assemblies, including the VG7241ST+7202G and VG7241ST+916GGA series.
• Steam Rated Performance: Suitable for low-pressure steam applications up to 35 psig at 281°F, covering a broad range of mechanical room requirements.

What is the close-off pressure for this 2-inch valve?
The VG7241ST+71CHGA provides a close-off pressure of 46 psi, which is standard for the 2-inch VG7000 series when paired with the 180 lb-f VA7810 actuator.

Can I use this valve for steam applications?
Yes, this brass trim globe valve is rated for saturated steam up to 35 psig and fluid temperatures ranging from 35°F to 281°F.

Is the actuator failsafe?
This is a non-spring return actuator, meaning it will remain in its last position if power is lost. For applications requiring a failsafe open or closed position, a spring-return model would be required.
