Johnson Controls VG1245FSH958BGA Valve Assembly

The Johnson Controls VG1245FSH958BGA is a heavy-duty, 2-inch normally closed ball valve assembly engineered for precise control in commercial HVAC systems. This 2-way NPT ball valve features a forged brass body and 300 series stainless steel trim, making it highly resistant to corrosion and suitable for chilled water, hot water, and low-pressure steam applications up to 15 psi. Utilizing a 46.8 Cv equal percentage flow characteristic, this assembly ensures linear heat transfer and stable temperature regulation under varying load conditions. It is equipped with a VA9208-BGA-3 spring return actuator, providing reliable fail-safe operation upon power loss. The integrated thermal barrier and high-temperature linkage protect the actuator from heat transfer, extending the service life of the 24V motor. With a 200-psi close-off rating and maintenance-free design rated for 200,000 cycles, this unit is a reliable choice for automated flow control in demanding mechanical environments.

• Precision Flow Control: The 46.8 Cv equal percentage disk provides accurate throttling for consistent temperature management.
• Fail-Safe Reliability: Integrated spring return ball valve mechanism ensures the system defaults to a closed position during power interruptions.
• Steam-Rated Durability: Stainless steel ball and stem construction allows for use in saturated steam applications up to 15 psig.
• Actuator Protection: High-temperature linkage and thermal spacer mitigate heat damage in high-temp water and steam loops.
• Leak-Free Operation: Dual EPDM O-ring stem seals and graphite-reinforced PTFE seats deliver tight shutoff and superior cycle life.

What is the maximum close-off pressure for this assembly?
This 2-way valve is rated for a maximum close-off pressure of 200 psi, ensuring reliable shutoff even in high-pressure hydronic systems.

Can this valve be used for steam applications?
Yes, because this model features stainless steel trim (FSH configuration), it is suitable for low-pressure saturated steam up to 15 psig.

Is the actuator field-reversible?
The VA9208 actuator is designed for two-position control and provides fail-safe spring return action to the normally closed position for this specific assembly.
