Trane 5AYTXVH3A6000A Txv Kit 5 Ton R-454B Coil and Air Handler

Product Description

The Trane 5AYTXVH3A6000A is a thermostatic expansion valve (TXV) kit rated for 5-ton systems and calibrated for R-454B refrigerant. The TXV meters refrigerant flow into the evaporator coil in response to superheat, keeping the coil loaded efficiently without flooding the compressor. This kit is intended for use with coil and air handler assemblies and is installed by licensed HVAC technicians during new system commissioning or as a replacement on existing equipment. Proper TXV sizing and refrigerant compatibility are critical to system efficiency and equipment longevity, making this an OEM-sourced solution for R-454B applications.

This kit is designed for residential and light commercial split-system applications where R-454B is the specified refrigerant. R-454B is an A2L low-GWP refrigerant increasingly required by new efficiency and environmental regulations, and this TXV is engineered specifically for its thermodynamic properties. The 5AYTXVH3A6000A appears as a listed TXV kit option alongside 5AYTXVH3A1836A and 5AYTXVH3A4248A in Trane installer documentation (guide 18-HE141D1-1A-EN), covering the 60,000 BTU/h capacity range. It has also been specified as part of complete 5-ton split-system configurations including the A5AC4060A1000 condenser.

Key Features

• Rated for 5-ton (60,000 BTU/h) coil and air handler assemblies
• Calibrated specifically for R-454B refrigerant — not interchangeable with R-410A valves
• Thermostatic expansion valve design regulates superheat for stable evaporator performance
• Mountable in any position on the evaporator coil inlet
• OEM Trane part, referenced in Trane installer guide 18-HE141D1-1A-EN

Compatibility

Listed in Trane installer documentation (18-HE141D1-1A-EN) as part of the R-454B TXV kit series alongside 5AYTXVH3A1836A and 5AYTXVH3A4248A. Also referenced in 5-ton split-system configurations using the A5AC4060A1000 condenser. Intended for coil and air handler assemblies requiring a 5-ton R-454B TXV. Do not substitute for R-410A or other refrigerant-specific valves without verifying system design specifications.

Installation Notes

Installation must be performed by an EPA Section 608-certified HVAC technician. Recover all refrigerant from the system before opening any refrigerant circuit, and follow all national, state, and local codes as outlined in the Trane installer guide. The TXV can be mounted in any orientation on the evaporator coil inlet, but confirm that bulb placement and equalizer line connections meet the coil manufacturer's requirements before recharging. Never mix R-454B with other refrigerants, and use only tools and components rated for A2L refrigerant service.
