ABSTRACT:
A filter head for use in cooperative engagement with an associated liquid filter comprises a block member having a bypass valve assembly, and a back pressure flow valve assembly. The block member defines an inlet port; an inlet channel positioned for fluid communication between the inlet port and the associated liquid filter; a first outlet port; a second outlet port; and an outlet channel positioned for fluid communication between the associated liquid filter and the first and second outlet ports. When in an open orientation, the bypass valve provides fluid communication between the inlet channel and the outlet channel. When in a closed orientation, the bypass valve blocks fluid communication between the inlet channel and the outlet channel. The back pressure flow valve assembly, when in an open orientation, provides fluid communication between the outlet channel and the second outlet port. When in a closed orientation, the back pressure flow valve assembly blocks fluid communication between the outlet channel and the second outlet port.
