4 4/14 SEW Directionl set vlve Function, sections, symols: 2/2 nd 3/2 directionl set vlve Generl he SEW type directionl vlve is directionl set vlve with solenoid ctution. It controls strt, stop nd flow direction. he vlve siclly consists of the housing (1), the solenoid (2), the hrdened vlve system (3) s well s the ll/ the spool (4) s closing element. Bsic principle In the initil position, the ll/the spool (4) is pressed onto the set y the spring (9) nd in the switching position y the solenoid (2). he force of the solenoid (2) cts vi the ngled lever (6) nd the ll (7) on the ctuting plunger (8) tht is seled on two sides. he chmer etween the two seling elements is connected to port. herefore, the vlve system (3) is pressure-compensted in reltion to the ctuting forces (solenoid or return spring). his mens the vlves cn e used up to 630 r. Notices! 3/2 directionl set vlves feture "negtive spool overlp". herefore, port must lwys e connected. ht mens tht during the switching process from the strting of the opening of one vlve set to the closing of the other vlve set ports re connected with ech other. However, this process tkes plce within such short time tht it is irrelevnt in nerly ll pplictions. he mnul override (10) llows for the switching of the vlve without solenoid energiztion. Mke sure tht the specified mximum flow is not exceeded! Use throttle insert for limiting the flow, if necessry (see pge 13).

Function of the lus-1 plte Initil position: he min vlve is not ctuted. he spring (9) holds the ll (4.1) on the set (11). ort is locked nd is connected to. prt from tht, one pilot line is connected from to the lrge re of the control spool (12), which is thus unloded to the tnk. he pressure pplied vi now pushes the ll (13) onto the set (14). Now, is connected to B, nd to. rnsition position: When the min vlve is ctuted, the spool (4.2) is shifted ginst the spring (9) nd pressed onto the set (15). ort is closed;,, nd B re riefly connected to ech other. Spool position: is connected to. s the pump pressure cts vi on the lrge re of the control spool (12), the ll (13) is pressed onto the set (16). herefore, B is connected to, nd to. he ll (13) in the lus-1 plte hs "positive spool overlp". Notice! If the nnulus re of differentil cylinders is not connected to port, pressure pek is creted in port B during the switching process due to the pressure intensifiction. his pressure pek my exceed the mximum operting pressure over the permissile limit.
