Johnson Controls VG7241RT+3008BP Valve Assembly

The Johnson Controls VG7241RT+3008BP is a heavy-duty 1-1/2 inch NPT globe valve assembly designed for high-performance modulation in commercial HVAC systems. This 2-way normally open pneumatic valve features a cast bronze body with durable brass trim, engineered to handle steam and water applications with a 28.9 Cv rating. The equal percentage flow characteristic ensures precise throttling control, preventing hunting in the loop. It is equipped with a spring return exposed pneumatic actuator featuring a 3-6 PSI spring range and an integrated pneumatic positioner, which provides the necessary torque and feedback to overcome high close-off pressures. This VG7000 series valve is a standard-setter for contractors seeking reliable pneumatic valve replacement options that integrate seamlessly with existing BAS pneumatic lines. The combination of the MP82 series actuator and the bronze seating provides a robust solution for rigorous mechanical room environments where durability is non-negotiable.

• High-Flow Capacity: The 28.9 Cv rating allows for significant volume throughput in 1.5 inch piping systems.
• Precise Modulation: Integrated pneumatic positioner ensures the valve plug matches the controller’s output exactly, regardless of friction or line pressure.
• System Safety: Spring return action ensures the valve defaults to the open position during a loss of control air, protecting critical heat exchange processes.
• Rugged Construction: Cast bronze body and brass trim provide superior corrosion resistance and longevity in hydronic heating or cooling loops.

Common Questions Regarding the VG7241RT+3008BP

What is the maximum fluid temperature for this assembly?
This Johnson Controls VG7000 assembly is typically rated for saturated steam up to 338°F and water temperatures ranging from 35°F to 281°F, depending on the specific packing used.

Can the actuator be serviced without removing the valve body?
Yes, the exposed pneumatic actuator design allows for field maintenance or actuator replacement without breaking the 1-1/2" NPT pipe connections.

Does this unit come calibrated?
The 3-6 PSI spring range and positioner are factory-set but should be verified in the field to match the specific pneumatic controller calibration on-site.
