ABSTRACT:
A multipiece control spool of a control valve is hooked together by hooks extending from the end surface of each spool member. At least one hook is provided with central plateaus that extend into beveled areas that allow for axial misalignment between hooked spool members. The end surface of one of the spool members is also provided with a central plateau and a recessed surface extending from the plateau, to further aid in allowing for axial misalignment.
