Johnson Controls VG7241RT+823C01 Valve Assembly

As an experienced HVAC technician, you know the importance of precise fluid control in commercial hydronic and steam systems. The Johnson Controls VG7241RT+823C01 is a 1-1/2 inch 2-way normally open globe valve configured for rigorous HVACR valve assembly demands. Built with a high-strength cast bronze body and durable brass trim, this Johnson Controls VG7000 series assembly is engineered for reliable modulation of hot water, chilled water, and up to 38 psig saturated steam. The 28.9 Cv rating and equal percentage flow characteristic ensure stable control even under varying load conditions. This unit features a spring-return pneumatic actuator with a factory-calibrated 3-7 psi spring range and an integrated V-9502-95 positioner for superior accuracy. Designed to meet ANSI Class 250 standards, the VG7241RT+823C01 provides the high close-off pressure and operational longevity required for heavy-duty institutional and industrial mechanical rooms.

• Precision Control: High-performance positioner ensures the valve reaches exact setpoints for optimal system efficiency.
• Rugged Construction: Cast bronze body and brass trim provide excellent corrosion resistance in water and steam applications.
• Reliable Failsafe: The normally open, spring-return pneumatic actuator ensures the valve returns to the open position upon loss of air pressure.
• High Flow Capacity: A 28.9 Cv rating allows for significant flow with minimal pressure drop across the 1-1/2" NPT connection.
• Standardized Compatibility: Fully compliant with ANSI Class 250 pressure and temperature specifications for seamless integration.

What media is this valve assembly compatible with?
This assembly is rated for hot water, chilled water, 50% glycol solutions, and saturated steam up to 38 psig, making it ideal for most commercial HVACR applications.

Does the pneumatic positioner require special calibration?
The integrated V-9502-95 positioner is designed for high-resolution control but should be verified for zero and span calibration during commissioning to match your specific 3-7 psi controller signal.

Can the packing be serviced without removing the valve body?
Yes, the VG7000 series is designed for technicians, allowing for in-line serviceability, including valve repacking, which minimizes downtime during routine maintenance.
