HYDRAULIC SPECIFICATIONS SPECIFICHE IDRAULICHE Parallel circuit Circuito Parallelo When the spool is operated it intercepts the switch gallery by diverting the flow of oil to service port A or B. If two or more spools are actuated at the same time, the oil will power the service port that has the lower load by selecting the path with the least resistance; by throtting the spools, the flow of oil can be divided between two or more service ports.
