Johnson Controls VG7882ET Valve

The Johnson Controls VG7882ET is a precision-engineered 1/2 inch 3-way mixing globe valve designed for demanding HVAC applications requiring accurate flow control of water or glycol solutions. Built with a rugged cast bronze body and brass trim, this valve features a 1.8 Cv linear flow characteristic, making it ideal for terminal unit applications where consistent temperature modulation is critical. The union sweat connection with standard tubing ensures a secure, leak-free installation in tight mechanical spaces. Engineered with a standard threaded stem, it integrates seamlessly with VA series actuators to provide reliable mixing of hot or chilled water. This HVAC mixing valve is built to withstand the rigors of commercial piping systems, ensuring long-term performance and minimizing pressure drops across the coil. Contractors prefer this VG7000 series valve for its field-proven reliability and ease of integration into existing building automation systems.

Key Benefits

• Precise Modulation: The 1.8 Cv rating and linear flow characteristic provide stable control for fan coil units and heat pumps.
• Durable Construction: Cast bronze body and brass internal components offer superior resistance to corrosion and wear.
• Efficient Installation: Union sweat connections simplify the fitting process for standard copper tubing, reducing labor time.
• Actuator Compatibility: Features a standard threaded stem designed for direct-mount compatibility with electronic and pneumatic actuators.

Common Questions

What is the maximum operating temperature for the VG7882ET?
This valve is designed to handle fluid temperatures ranging from 35°F to 284°F (2°C to 140°C), depending on the specific actuator and packing selection.

Can this 3-way valve be used for diverting applications?
The VG7882ET is specifically designed as a mixing valve, where two inlets are combined into one outlet. Using it for diverting purposes may cause water hammer and reduce internal seal longevity.

What type of maintenance is required for the valve stem?
The Johnson Controls VG7000 series typically utilizes a spring-loaded V-ring packing that is self-adjusting, minimizing the need for frequent field maintenance or tightening.
