Johnson Controls VG7241ST+823C00 Valve Assembly

The Johnson Controls VG7241ST+823C00 is an industrial-grade, 2-inch NPT threaded globe valve assembly designed for precise modulation in high-demand HVACR systems. This 2-way normally open valve features a 46.2 Cv rating with an equal percentage flow characteristic, ensuring stable control of hot water, chilled water, or saturated steam up to 38 psig. The assembly integrates a rugged cast bronze body with durable brass trim and EPDT U-cup packing for superior sealing and longevity in demanding environments.

Actuation is handled by a factory-mounted MP82 series pneumatic actuator, utilizing a 3-7 psi spring range for reliable spring return safety. This 25 sq. in. diaphragm actuator provides the necessary force to maintain tight shut-off against high differential pressures. Specifically engineered for proportional control, the VG7241ST+823C00 excels in air handling units and heat exchangers where linear response to controller demand is critical for occupant comfort and energy efficiency.

• High Flow Capacity: The 46.2 Cv rating supports significant flow rates for large-scale hydronic and steam applications.
• Enhanced Durability: Cast bronze body construction with an electro-painted finish resists corrosion and ensures structural integrity in high-temperature service.
• Precise Modulation: Equal percentage flow characteristic provides predictable linear thermal output across the valve stroke.
• Failsafe Operation: Relies on a pneumatic spring return mechanism to revert the valve to its normally open position during a loss of control air.
• Technical Compliance: Built to ANSI Class 250 standards, ensuring high static pressure ratings and reliable service life in commercial HVAC systems.

What media can this valve assembly handle?
The VG7241ST+823C00 is rated for hot water, chilled water, and saturated steam up to 38 psig, with a fluid temperature range of 35°F to 284°F.

Is this valve suitable for high-pressure systems?
Yes, the valve body is rated for ANSI Class 250 static pressure, making it a robust choice for multi-story commercial buildings and industrial loops.

Can I add a positioner to this assembly?
The MP82 actuator can be field-retrofitted or ordered with a V-9502-95 pneumatic positioner for applications requiring even tighter control accuracy.
