Johnson Controls VG7842LT Valve

The Johnson Controls VG7842LT is a heavy-duty, 3-way mixing globe valve specifically engineered for precision flow control in terminal unit applications. Featuring a high-quality cast bronze body and durable brass trim, this 3/4-inch NPT valve is designed to manage hot water, chilled water, and saturated steam up to 38 psig. With a 7.3 Cv rating and a linear flow characteristic, it provides stable and predictable mixing performance across its entire stroke, ensuring optimal heat transfer and system efficiency in complex HVACR loops.

Built on the VG7000 Series platform, the VG7842LT utilizes a standard threaded stem compatible with a wide range of electric and pneumatic actuators, such as the VA-4233 or M9000 series. Its robust construction meets ANSI Class 250 pressure and temperature standards, supporting fluid temperatures from 35°F to 284°F. This valve is the professional choice for contractors looking for a reliable, field-serviceable mixing component that offers superior rangeability and tight close-off in demanding hydronic environments.

• Precision Mixing Performance: The 3-way mixing configuration and linear flow design provide accurate temperature control for consistent coil output.
• Industrial-Grade Durability: The cast bronze body and brass trim are resistant to corrosion, significantly extending the service life in bypass or mixing applications.
• High Capacity: A 7.3 Cv rating allows for efficient fluid handling in 3/4-inch branch lines without excessive pressure drop.
• Versatile Compatibility: Designed for seamless integration with Johnson Controls actuators, facilitating easy field installation and setup.

• Can the VG7842LT be used for diverting applications? No, this is a 3-way mixing valve designed for two inlets and one outlet. Using a mixing valve for diverting can lead to noise and premature seat wear.
• What is the maximum steam pressure rating? This valve is rated for saturated steam up to 38 psig, making it suitable for low-pressure steam heating systems.
• Is the packing replaceable? Yes, the VG7000 Series features a serviceable design, allowing for in-line repacking to maintain tight seals over long-term operation.
