A magnetically latched reversing valve for a heat pump is provided. The reversing valve imparts an axial force on a flux ring, the flux ring being integrated into a sliding valve spool as a magnetically latched, two position reversing valve. In particular, the flux ring moves axially in response to an electromagnetic field generated by a solenoid coil, while a radially-magnetized permanent magnet provides the latching force to hold the flux ring in position. The flux ring is disk-shaped or ring-shaped, being movable in fixed relation with the valve spool. The reversing valve consumes electrical power only during the switching process, not while maintaining the valve position. This reduced power consumption leads to reduced heat generation, and the reversing valve maintains its position even in the event of a power failure, ensuring its reliability.
