<strong>HV18</strong> <strong>Series</strong>Monoblock Lever ValvesMain Relief ValvePPP2P2Inlet with Main Relief ValveInlet without Main Relief ValveHydraulic CircuitParallel CircuitWhen the spool is operated, it intercepts theswitch gallery by diverting the flow of oil toservice port A or B. If two or more spools areactuated at the same time, the oil will powerthe service port that has the lower load byselecting the path with the least resistance;by throtting the spools, the flow of oil can bedivided between two or more service ports.P2P102A1 B1102A2 B2TT2<strong>Series</strong> CircuitWhen the spool is operated, it intercepts theswitch gallery by diverting the flow of oil toservice port A or B. The oil that flows backfrom the actuator is carried to the switchgallery thus making it available to the serviceports downstream from the series section.The pressure drop downstream is added tothe pressure drop of the section itself.P2P102A1 B1102A2 B2TT231341 Friendship Drive, Magnolia, TX 77355 • Tel.: 281-259-7768 Fax: 281-259-7249 • www.hyvair.com
