Abstract
A filtration system comprises a housing and a shell housing removably coupled to the housing. A valve comprise a valve housing and a plunger. The plunger comprises a seal member structured to seal an opening in the valve housing. The plunger is axially movable between a closed position, in which the seal member seals the opening, and an open position, in which the seal member does not seal the opening, thereby permitting fluid to flow through the valve housing. A filter element comprises filter media and an endcap. The endcap comprises an alignment tab configured to rotationally secure the filter element with respect to the shell housing when the shell housing is received in the housing. The endcap comprise a valve interaction projection structured to transfer rotation of the filter element and the shell housing to the plunger during installation of the filter element.
