4 HV8 Series Main Relief Valve Inlet with Main Relief Valve Inlet without Main Relief Valve Hydraulic Circuit arallel Circuit When the spool is operated, it intercepts the switch gallery by diverting the flow of oil to service port or. 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. T T Series Circuit When the spool is operated, it intercepts the switch gallery by diverting the flow of oil to service port or. The oil that flows back from the actuator is carried to the switch gallery thus making it available to the service ports downstream from the series section. The pressure drop downstream is added to the pressure drop of the section itself. T T 334 Friendship Drive, Magnolia, TX Tel.: Fax:
