<p>A modular hydraulic valve is disclosed, which comprises a valve manifold and a number of valve cartridge elements disposed at least partly within cavities defined in the valve manifold. To encourage interchangeability and reduce manufacturing costs, each cavity includes a number of axially aligned steps of progressively decreasing diameter. The outermost steps of each cavity is defined by a diameter identical with the outermost step diameter of all other cavities, regardless of whether those other cavities define one or more than one additional steps. Likewise, the second outermost step in each cavity is defined by another diameter which is substantially identical with the second step diameter of all other cavities having two or more steps.</p> |
