Johnson Controls VG7841CT Valve

The Johnson Controls VG7841CT is a precision-engineered 3-way mixing globe valve designed for demanding HVAC applications. Featuring a 1/2 inch NPT connection and a 0.73 Cv rating, this valve utilizes an equal percentage flow characteristic to provide stable modulating control in water or glycol systems. Built with a heavy-duty cast bronze body and brass trim, the VG7841CT is designed for long-term reliability in hydronic heating and cooling loops.

As part of the reputable VG7000 series, this model includes a standard threaded stem for seamless integration with a variety of Johnson Controls electric or pneumatic actuators. The mixing configuration allows for precise fluid temperature regulation by blending two inlet streams. With its robust construction, the VG7841CT valve maintains high performance under varied pressure drops, making it a staple for contractors looking for field-proven bronze control valves.

Key Benefits

• Equal Percentage Flow: Ensures linear heat transfer and stable control across the entire stroke of the Johnson Controls VG7841CT.
• Durable Construction: The cast bronze body and brass trim resist corrosion and wear in standard hydronic applications.
• Versatile Compatibility: Designed for use with both electric and pneumatic actuators, facilitating easy field upgrades or replacements.
• High Precision: The 0.73 Cv capacity is ideal for low-flow terminal unit control where accuracy is paramount.

Common Questions

• Can this 3-way valve be used for diverting? No, the VG7841CT is specifically designed as a 3-way mixing valve; using mixing valves for diverting applications can lead to premature seat wear and noise.
• What media is compatible with this globe valve? It is rated for hot water, chilled water, and up to 50% glycol solutions within a temperature range of 35?F to 284?F.
• Does this require a specific actuator? This valve features a standard threaded stem that fits most Johnson Controls VA series actuators, though always verify the required close-off pressure for your specific application.
