Johnson Controls VG1245FSH958BAA Valve

For high-demand HVAC mechanical rooms, the Johnson Controls VG1245FSH958BAA offers a robust solution for automated fluid control. This 2-inch 2-way normally closed ball valve assembly is engineered with a forged brass body and 300 series stainless steel trim, ensuring longevity when handling chilled water, hot water, or 15 psig saturated steam. The spring return electric actuator provides a reliable fail-safe position, while the 120Vac power supply integrates seamlessly into standard electrical infrastructures. Utilizing an Amodel flow characterizing disk, this actuated ball valve delivers 46.8 Cv with an equal percentage flow characteristic, allowing for precise modulation and stable hunting-free performance across 500:1 rangeability. The inclusion of a thermal barrier protects the actuator from extreme media temperatures, extending the life of the internal components in high-heat applications.

Key Benefits:

• Precision Control: Features an equal percentage flow characteristic for refined temperature management in complex hydronic systems.
• Saturated Steam Compatibility: The stainless steel trim allows for 15 psi steam service, far exceeding the capabilities of standard brass-trim valves.
• Industrial Endurance: Tested for over 200,000 cycles in iron-oxide contaminated water, featuring graphite-reinforced PTFE seats for superior wear resistance.
• Fail-Safe Protection: Reliable spring return mechanism ensures the valve returns to a safe, normally closed state during power loss.
• Thermal Isolation: Integrated thermal barrier allows the assembly to handle fluid temperatures ranging from -22°F to 284°F.

Common Questions:

Can this valve be used for steam applications?
Yes, because this specific SKU features stainless steel trim, it is rated for up to 15 psig saturated steam service, unlike models with chrome-plated brass balls.

What is the purpose of the thermal barrier?
The thermal barrier provides critical air space and insulation between the valve body and the actuator, preventing high media temperatures from damaging the 120V electrical components.

Does this assembly provide a tight shut-off?
Yes, the VG1000 series ball valves are designed for a close-off pressure rating of 200 psi, ensuring ANSI Class IV leakage protection and preventing unintended bypass.
