Application
The VAL9406 is the correct OEM replacement TXV for compatible Trane and American Standard air conditioning and heat pump systems operating on R-410A refrigerant at 5-ton capacity. Always verify compatibility with the original equipment model number before installation.
Why Choose an OEM Trane TXV?
Using a genuine Trane replacement valve ensures proper refrigerant metering calibrated to your specific system’s design parameters. An incorrectly sized or mismatched TXV can result in poor system performance, elevated energy consumption, and premature compressor failure. The VAL9406 eliminates these risks by providing a factory-matched solution.
