The FRIEDRICH 67401389 is a thermal expansion valve (TXV) body designed as a direct OEM replacement component for Friedrich cooling and heat pump systems. The TXV body meters refrigerant flow into the evaporator coil, maintaining the correct superheat level across varying load conditions. This part is sold individually and is installed by licensed HVAC technicians during system service or refrigerant-side repairs. Proper TXV function is critical to system efficiency, evaporator performance, and compressor protection.
This valve body is specified for use with the Friedrich model WFH60Z223C. It is suited for refrigerant-side service on that system, typically performed during a refrigerant circuit repair, component replacement after failure, or system rehabilitation. Installation requires recovery of the existing refrigerant charge before any component removal.
Designed for use with Friedrich model WFH60Z223C.
Installation must be performed by an EPA Section 608 certified HVAC technician. Recover all refrigerant from the system before removing the existing TXV body. Follow standard brazing or connection procedures as required by the system design, and pressure-test the refrigerant circuit before recharging. Refer to the equipment service manual for system-specific procedures.
