  • The most common circuit is the parallel circuit. In this design, when any one of the spools is shifted, it blocks off the open center passage. Oil then flows into the parallel circuit core, making oil available to all spools. If more than one spool is shifted, the oil will flow to the path of least resistance. When a spool is shifted in tandem, also referred to as a priority circuit, oil is cut off to all downstream sections. Thus, the section nearest to the inlet has priority over the other sections. If more than one spool is shifted, all the oil will go to the section nearest to the inlet. - [1]
  • Series, partial series, parallel - [2]
  • Cylinder regeneration mode?
  • Is a regular valve series or paralle? Such as [3]
  • Reading this implies that all the spools on a single valve operate in parallel [4]
