Zusammenfassung:	A rotary vacuum valve for distributing vacuum pressure to one or more air-tight enclosures of a rotary vacuumization system, wherein the rotary valve comprises:a stationary portion defining an entry port in fluid communication with a vacuum system and a diagnostic port in fluid communication with a diagnostic system; anda rotating portion defining a plurality of chamber ports each in fluid communication with a corresponding vacuum chamber via a vacuum conduit, wherein each vacuum chamber is configured to form an air-tight enclosure;wherein the rotating portion is configured to rotate relative to the stationary portion and thereby selectably align each of the plurality of chamber ports with the one or more entry ports of the stationary portion to place the corresponding vacuum chamber in fluid communication with the vacuum system and to selectably align each of the plurality of chamber ports with the diagnostic port to place the corresponding vacuum chamber in fluid communication with the diagnostic system.
