Johnson Controls VG1245FTH958BAA Valve Assembly

This Johnson Controls VG1245FTH958BAA is a commercial-grade 2-inch 2-way normally closed ball valve assembly designed for demanding HVAC applications. Engineered with a forged brass body and 300 series stainless steel trim, this unit is built to manage hot water, chilled water, and 50/50 glycol solutions, and is even rated for low-pressure steam up to 15 psi. The thermal barrier provides necessary insulation between the 120Vac spring return actuator and the valve body, protecting the electronics in high-temperature environments. With a high 73.7 Cv flow coefficient and an integrated Amodel flow characterizing disk, this assembly ensures precise equal percentage flow control, which is essential for maintaining stable discharge air temperatures in air handling units and large heating coils. The dual EPDM O-ring stem seals offer reliable, leak-free performance, while the 500:1 rangeability allows for granular modulation across various load conditions.

• High-Capacity Performance: The 73.7 Cv rating enables significant fluid throughput, ideal for large-bore 2" NPT piping systems.
• Superior Metallurgy: Stainless steel ball and stem trim provides enhanced corrosion resistance compared to standard chrome-plated options, particularly in 15 psi steam service.
• Fail-Safe Security: The spring return actuator ensures the valve returns to its normally closed safety position during power loss.
• Thermal Protection: A dedicated thermal barrier extends the operational life of the actuator by isolating it from fluid heat up to 250°F.
• Precise Control: Features an Amodel disk for equal percentage flow, preventing the erratic control often associated with standard ball valves.

• Is this valve suitable for steam applications? Yes, because it features stainless steel trim and a thermal barrier, it is rated for saturated steam up to 15 psig.
• What is the close-off pressure rating? This assembly provides a high close-off pressure of up to 200 psi, ensuring tight shut-off and preventing ghost flows in the system.
• Can the actuator be replaced in the field? Yes, the VG1000 series design allows for straightforward actuator swaps or upgrades without removing the valve body from the line.
