ABSTRACT:
The improved valve apparatus is particularly useful in connection with fluid filtering using a cartridge. The apparatus includes a valve body with inlet and outlet ports and a rotatable spool mounted in the body. The spool has an angularly affixed seal member which directs fluid flow. When the spool is in one position, fluid is directed along a flow path which includes the inlet port, the cartridge and the outlet port. When the spool is in the other position, fluid is directed along another flow path which includes the ports but which bypasses the cartridge. In that way, the cartridge can be replaced without interrupting continuity of flow.
