Johnson Controls VG78K2NT Reconditioning Kit

The Johnson Controls VG78K2NT Reconditioning Kit is a professional-grade field service solution designed to restore the performance of 1-inch VG7000 Series 3-Way Mixing Valves. Engineered specifically for valves with an 11.6 Cv rating and brass trim, this kit addresses common failure points such as internal scaling, seat leakage, and packing wear. It features linear flow characteristics to ensure precise modulation through the threaded stem assembly, maintaining critical control loop stability in hydronic systems. This valve repair kit is essential for mechanical contractors looking to avoid full valve body replacement, reducing labor hours and material costs. By replacing the stem and plug assembly alongside the high-quality packing, you ensure the assembly meets original factory specifications for drop-tight shutoff. Utilizing a VG78K2NT service kit preserves the integrity of the mixing valve configuration, particularly in demanding commercial HVAC applications where bypass flow accuracy is vital.

• Field Restoration: Enables complete internal overhaul of Johnson Controls VG78K2NT assemblies without removing the valve body from the piping.
• Optimized Flow Control: Precision-machined brass components maintain the 11.6 Cv flow coefficient and linear performance.
• Threaded Stem Integration: Ensures seamless mechanical connection with VG7000 series actuators for reliable stroke transition.
• Durable Sealing: Includes industrial packing designed to withstand fluid temperature fluctuations and prevent external stem leaks.

Will this kit work with stainless steel trim valves?
No, the VG78K2NT is specifically engineered for brass trim configurations. Using brass internal components in a stainless steel valve body may lead to premature wear or galvanic corrosion.

Can this reconditioning kit be used for diverting applications?
This kit is designed for 3-way mixing valves. While the physical dimensions may appear similar, the internal plug geometry is specific to mixing flow patterns.

Does this kit include the replacement packing?
Yes, the kit provides the necessary stem and packing components to resolve common HVAC valve repair issues related to stem leakage.
