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. HYDRAULIC SCHEMA Il cursore quando viene azionato, intercetta il canale di libera circolazione deviando il flusso d’olio agli utilizzi A o B. Se due...

HYDRAULIC SPECIFICATIONS Carry-over connection (HPCO) SPECIFICHE IDRAULICHE Collegamento carry-over (HPCO) This option, available on all HC-D9, allows the monoblock to feed a second valve, by extending the free flow channel. In this configuration, the valve needs a separated port for the connection to tank. Questa opzione, di serie sul distributore HC-D9, permette il prolungamento del canale di libera circolazione all’esterno, alimentando così un secondo distributore. Il distributore così configurato necessita di uno scarico per le utenze. It is possible to transform sectional valve from...
