Johnson Controls VG7842GS Valve

The Johnson Controls VG7842GS is a professional-grade 1/2" 3-way globe mixing valve engineered for precise fluid modulation in high-demand HVAC and hydronic systems. Built with a rugged cast bronze body and brass trim, this VG7000 Series mixing valve provides superior control for hot water, chilled water, and 50/50 glycol solutions. With a 4.6 Cv flow coefficient and a linear flow characteristic, it ensures stable temperature regulation across its 35°F to 248°F fluid range. This model features a slotted stem and a small bonnet design, specifically optimized for compact installations where space is at a premium. Rated for ANSI Class 250, it handles static pressures up to 400 psig (at 150°F), making it a reliable choice for commercial hydronic mixing or diverting applications. Whether you are replacing an existing unit or building out a new terminal unit loop, the VG7842GS globe valve delivers the durable performance required for long-term industrial service.

Key Benefits for Facilities and Contractors

• Precision Modulation: The 4.6 Cv linear flow design allows for fine-tuned temperature control in terminal unit applications.
• Durable Construction: Cast bronze body and brass trim offer high resistance to corrosion and wear in glycol-treated systems.
• High Pressure Resilience: Rated for ANSI Class 250, supporting high-rise and large-scale commercial pressure requirements.
• Compact Footprint: The small bonnet design and 1/2" NPT connections facilitate easy integration into tight mechanical closets.
• Actuator Compatibility: Designed for seamless field or factory mounting with Johnson Controls VA-805x and V-3801 series actuators.

Common Questions

Is the VG7842GS suitable for steam applications?
Yes, this brass-trim valve is rated for 15 psig saturated steam, making it versatile for both hydronic and low-pressure steam systems.

Does this valve include a motor or actuator?
No, the VG7842GS is the valve body only. You must pair it with a compatible Johnson Controls electric or pneumatic actuator for automated control.

Can I use this valve for diverting flow instead of mixing?
While primarily designed as a mixing valve (two inlets, one outlet), it can be used in certain diverting configurations depending on the system pressure and the specific actuator linkage used.
