Application

The VAL8712 is intended as a direct OEM replacement for Trane split-system air conditioners and heat pumps using R-22 refrigerant at 1-ton capacity. Its 3/8 in. liquid-line inlet and 1/2 in. distributor outlet make it compatible with standard Trane evaporator coil assemblies. The 55/51# spring setting ensures the valve opens and closes at the correct differential pressure to maintain optimal superheat throughout the operating range.

Why Choose a Trane OEM TXV?
