Johnson Controls VG7241PT+3008D Valve Assembly

The Johnson Controls VG7241PT+3008D is a rugged 1-1/4 inch NPT globe valve assembly designed for precise HVAC pneumatic control of hot water, chilled water, or steam. This 2-way normally open configuration features a cast bronze body and brass trim, ensuring high durability in demanding commercial environments. With an 18.5 Cv rating and equal percentage flow characteristic, it provides stable modulating control, making it a reliable choice for terminal unit control and air handling unit (AHU) applications. The assembly is driven by a 3-inch MP8000 series pneumatic actuator with a 4-8 PSI spring range, utilizing a spring return mechanism for fail-safe operation. This Johnson Controls VG7200 series valve is engineered for energy-efficient HVAC systems, providing excellent static pressure management and tight shut-off performance for professional hydronic heating and cooling installations.

• Equal Percentage Flow: Provides superior control loop stability over a wide range of flow rates.
• High Temperature Capability: Rated for saturated steam up to 38 psig and water temperatures up to 281°F.
• Pneumatic Reliability: The exposed pneumatic actuator ensures rapid response times and consistent cycling.
• Direct Compatibility: Standard NPT threaded connections allow for seamless integration into existing commercial HVAC piping.

Common Questions

What is the fail-safe position of the VG7141PT+3008D?
This specific assembly is 2-way normally open (N.O.), meaning the valve will default to the open position upon loss of control air pressure.

Can this valve be used for steam applications?
Yes, the VG7241PT+3008D is suitable for steam applications, provided the pressure does not exceed the 38 psig rating for the bronze body and brass trim configuration.

What is the purpose of the 4-8 PSI spring range?
The 4-8 PSI range defines the pressure required to move the actuator through its full stroke, allowing for precise sequencing in complex pneumatic control systems.
