Nordyne 669465R Reversing Valve

Professional-grade refrigeration service requires precise component matching, and the Nordyne 669465R Reversing Valve is the engineered OEM replacement part for critical heat pump restorations. This 4-way refrigerant reversing valve is designed for high-performance heat pump systems, facilitating the seamless transition between heating and cooling cycles by accurately directing refrigerant flow. This specific Nordyne replacement valve features 1/2-inch liquid line and 3/4-inch suction line connections, ensuring a direct mechanical fit without the need for extensive field modifications. It serves as the updated substitute for legacy part numbers 668767 and 669465. Built to withstand the thermal stresses of modern HVACR applications, this Nordyne 669465R maintains system integrity and operational efficiency in demanding environments. Note that this component is a reversing valve without coil; the solenoid coil must be sourced separately or reused if in working condition. This valve is verified for use in several heat pump models, including ESH1BE4M1SP24K, ESH1BE4M1SP18K, and FSH3BF4M2SX24K series.
