Abstract
A filter includes a replaceable filter element cartridge in a housing. A valve is actuatable between a first condition passing dirty fluid from the housing inlet to the filter cartridge for filtration, and a second condition blocking passage of the dirty fluid from the inlet to the filter cartridge. The filter cartridge and the valve engage in keyed relation, with the keying feature utilizing an identifier, e.g. a brand, a logo, etc., verifying authenticity of the filter cartridge.
