ABSTRACT:
A filter with installation integrity permits fluid flow only in a first installation condition and not in a second undesired or mis-installation condition, including improper alignment or mounting of a filter element in a housing, an incorrect replacement filter element, absence of a filter element, and an incorrect housing cover. A magnetically actuated valve has a piston controlling fluid flow according to installation condition.
