Application
The Trane VAL8719 TXV is the ideal direct OEM replacement for Trane and American Standard split-system air conditioners and heat pumps using R410A refrigerant. Proper TXV selection and installation is critical to system performance — this valve ensures the evaporator coil receives the correct refrigerant charge under varying load conditions, preventing both flooding and starving of the coil. Always verify system compatibility and follow all applicable refrigerant handling regulations during installation.
