Liquid valve Assembly

The Liquid Valve Assembly (Bosch PN 8733956449) is a refrigerant liquid-line service valve that provides a secure isolation point for system servicing, evacuation, and charge control. Field-replaceable and intended to simplify maintenance, it enables leak‑tight shutoff and service-port access so installers can service or commission equipment without disturbing other components. I could not locate official Bosch North America documentation for PN 8733956449 on the Bosch parts portals, so this description is based on the part name and Bosch parts‑category practices.
