Abstract: A valve assembly preferably including a housing having a recess and a flange face and a valve sleeve disposed within the recess. The sleeve preferably includes an annulus having an outer surface and an inner surface that defines a passageway about a central axis, the outer and inner surfaces being radially spaced from one another to define a wall. The wall has a first end portion and a second end portion axially spaced from the first end portion, and homogenous material properties from the first end portion to the second end portion. Preferably, the first end portion defines a lip for supporting the annulus in the recess and further defines a first chamber that encases at least a portion of a first support member. The second end portion preferably defines a flange portion along the outer surface for engaging the flange and further defines a second chamber that encases at least a portion of a second support member.
