Abstract
A spool valve section for a multiple valve assembly has a body with two opposing side surfaces. A plurality of mating surfaces are raised from each side surface. The mating surfaces surround the openings of fluid passages through the section and apertures for fasteners that secure the assembly together. The mating surfaces are spaced from a region of each side surface that is adjacent a bore in the body that receives a control spool. The fluid passages also are spaced from and do not intersect the spool bore. These characteristics of the spool valve section reduce distortion of the spool bore which could otherwise result from the pressure and fastening forces in the valve assembly.
