Zusammenfassung:A removable filter cartridge includes a filter housing containing a filter for filtering liquid and a sealing valve assembly coupled to the filter housing and for removably coupling the filter cartridge to a filter head. The sealing valve assembly include an inlet passageway and an outlet passageway. The sealing valve also including an inlet sealing valve that blocks the inlet passageway and an outlet sealing valve that blocks the outlet passageway while the filter cartridge is uncoupled from the filter head. A method of retrofitting a filter housing includes removing the filter housing from a filter head, coupling a sealing valve assembly to the removable filter to form a removable filter cartridge, and coupling the removable filter cartridge to the filter head.
