Bosch 4-way valve assembly (PN 8733956480) serves as an OEM-style replacement valve for reversing-cycle heat-pump systems, directing refrigerant between heating and cooling modes to restore proper mode switching. Intended for service technicians, the assembly integrates with standard refrigerant piping and control interfaces for straightforward replacement. I could not find PN 8733956480 in Bosch North America spare-part listings; this description is based on Bosch documentation of 4‑way/reversing valve function. (bosch-homecomfort.com)
