Johnson Controls VG7243NT+822D01 Valve Assembly

The Johnson Controls VG7243NT+822D01 is a high-performance 1-inch pneumatic globe valve assembly engineered for precise modulation in commercial HVACR systems. This 2-way normally open valve features a robust cast bronze body and stainless steel trim, delivering a 11.6 Cv flow coefficient with an equal percentage flow characteristic for stable control of hot water, chilled water, or 15 psig saturated steam. The integrated spring-return pneumatic actuator operates on a 4-8 PSI spring range and includes a factory-mounted pneumatic positioner to ensure accurate stem placement and repeatable performance under varying load conditions.

Designed for contractors prioritizing system longevity, the VG7000 series utilizes standard ring pack packings for a reliable seal and is tested for tight shutoff to maximize energy efficiency. The NPT threaded connections allow for straightforward integration into existing piping, while the normally open fail-safe position ensures flow is maintained during a loss of control air. This assembly is ideal for high-demand applications requiring corrosion-resistant valve trim and consistent proportional control.

• High Precision Control: The 11.6 Cv rating combined with equal percentage flow provides superior throttling for hydronic and steam applications.
• Durable Construction: Features a cast bronze body and stainless steel trim to resist wear and corrosion in demanding environments.
• Integrated Positioner: The pneumatic positioner ensures the actuator responds accurately to control signals, overcoming friction and unbalanced forces.
• Reliable Fail-Safe: The normally open spring return mechanical design ensures the valve defaults to the open position upon loss of air pressure.

Common Questions:

What is the maximum steam pressure for this valve?
This 1-inch assembly with stainless steel trim is rated for saturated steam applications up to 15 psig.

Is the positioner required for standard operation?
While the 4-8 PSI spring sets the range, the factory-installed positioner is essential for applications requiring precise modulation and faster response times in HVACR loops.

Can this valve be used for potable water?
No, this bronze valve contains lead and is designed strictly for closed-loop HVACR systems; it is not intended for drinking water applications.
