Johnson Controls vg74k1lt Recondition Kit DN20 Kv 3/4 Inch

Product Description

The Johnson Controls vg74k1lt is a recondition kit designed for DN20 KV series valves with a 3/4-inch configuration. This kit provides the necessary components to restore a worn or degraded valve assembly to serviceable condition, extending the operational life of the valve without requiring full valve replacement. It is typically installed in commercial HVAC and building automation systems where Johnson Controls control valves regulate flow of water or glycol in hydronic heating and cooling circuits. Installation is performed by qualified HVAC or building controls technicians.

This recondition kit is suited for use in hydronic systems where DN20 KV series valves have experienced wear to internal seals, seats, or other serviceable components. It is applicable in both light commercial and commercial building environments where maintaining precise flow control is critical to system efficiency and comfort. Use this kit during scheduled maintenance or as part of a corrective service call when valve performance has degraded.

Key Features

• Designed to recondition DN20 KV series control valves to restore proper operation
• 3/4-inch valve size compatibility for common hydronic piping configurations
• Extends valve service life, reducing the need for full valve replacement
• Suitable for hydronic heating and cooling applications in commercial HVAC systems

Compatibility

Designed as an OEM-style recondition kit for DN20 KV series control valves in a 3/4-inch configuration. Refer to Johnson Controls documentation to confirm fitment with your specific valve assembly before ordering.

Installation Notes

Installation should be performed by a licensed HVAC or building controls technician familiar with hydronic valve service. Shut down and isolate the hydronic circuit and relieve system pressure before disassembling the valve. Follow Johnson Controls service documentation for proper component sequencing during reassembly. Verify valve operation and check for leaks after returning the system to service.
