Johnson Controls VG7241RT+3008B Valve Assembly

The Johnson Controls VG7241RT+3008B is a heavy-duty 2-way normally open pneumatic valve assembly designed for precise flow control in commercial HVACR systems. Built with a 1 1/2 inch NPT connection and a robust cast bronze body featuring brass trim, this unit is engineered for longevity in demanding hydronic applications. The assembly utilizes a 28.9 Cv equal percentage flow characteristic, ensuring stable modulation and linear heat transfer across varying load conditions. It is equipped with a 3008B spring return pneumatic actuator operating on a 3-6 PSI spring range, providing reliable fail-safe performance. This VG7000 series valve is ideal for controlling hot water, chilled water, or 15 psig saturated steam. Contractors prioritize this globe valve assembly for its high close-off pressure ratings and compatibility with legacy pneumatic control sequences, ensuring seamless integration into existing terminal unit or air handling architectures.

Key Benefits:

• Precise Flow Regulation: The equal percentage flow plug design provides superior throttling for accurate temperature maintenance.
• Durable Construction: The cast bronze body and brass internal trim offer high resistance to corrosion and mechanical wear.
• Reliable Fail-Safe: The integrated spring return actuator ensures the valve returns to the open position upon loss of signal pressure.
• High Capacity: A 28.9 Cv rating allows for high volume flow with minimal pressure drop across the 1.5-inch port.

Common Questions:

What is the maximum fluid temperature for the VG7241RT+3008B?
This pneumatic globe valve is rated for water temperatures up to 281°F and saturated steam up to 15 psig, making it suitable for both heating and cooling loops.

Can this valve be field-serviced?
Yes, the VG7000 series allows for packing replacement and internal trim maintenance without removing the entire valve body from the piping system.

What air pressure is required for operation?
The 3008B actuator functions on a standard 3-6 PSI spring range, though high-pressure control signals may be used depending on the specific pneumatic controller calibration.
