The 4-way Valve Assembly (Part No. 8733956417) is a replacement component for Bosch reversible heat-pump systems that redirects refrigerant flow to switch between heating and cooling. As an OEM-style service assembly, it matches common Bosch valve interfaces and actuator connections to simplify field repairs and restore mode-change function with minimal system disruption. Search note: I could not find Bosch North America documentation for this part on bosch-homecomfort.com or bosch-climate.com; description based on four-way valve category knowledge.
