Abstract
An inner subassembly for assembling a valve assembly includes a spool defining a central bore that extends axially through the spool forming a spool annular wall, and including a spool cone tip that is disposed at the first axial end, as well as a hydraulic activation ridge extending radially outwardly from the spool annular wall, and that is disposed axially between the second axial end and the first axial end. The spool may further define a first bypass bore. A stem defines a first flow bore that aligns with the first bypass bore.
