Symol UK Symol CK 6 "" Model M-3SED 6 UKX/30CG24N9K sic function: he rrngement of the spring () determines the initil position of the vlve (open when de-energized "UK" or closed when deenergized"ck"). he chmer (3) ehind the closing element (4) is connected to port nd seled off from port. Hence the vlve is pressure-lnced with respect to the operting forces (solenoid nd spring). Due to the specil closing element (4) it is possile to pply the mximum operting pressure 076 SI (30 r) to ports, nd. he flow cn lso pss in oth directions (see symols)! In the initil position the closing element (4) is pressed onto set () y the spring (), in the switched position it is pushed onto set (7) y the solenoid (2). his results in lek-free closure. 7 Model M-3SED 6 CKX/30CG24N9K4 /2

Function of the plus- plte Initil position: he min vlve is not ctuted. he spring () holds the closing element (4) in its set (). ort is closed, nd port is connected to. In ddition, control line runs from to the lrge re of the control piston (8) so tht this is unloded to tnk. he pressure pplied vi now moves ll (9) onto set (0). is now connected to nd with. rnsition position: When the min vlve is operted, the closing element (4) is pushed ginst the spring () nd hence onto set (7). ort is, therefore, closed nd, nd re riefly connected. Shifted position: is connected to. s the pump pressure cts vi on the lrge re of the control piston (8), ll (9) is pushed onto set (2). hus, is connected to, nd to. he ll (9) in the plus- plte hs "positive shifting overlp". In order to void pressure intensifiction when single rod cylinders re used, the nnulus re of the cylinder must e connected to.

3 Generl notes R /06.98 Flow is only possile in the direction of the rrow, nd within the corresponding pressure limittions (see power limits on pge 4). In order to operte the vlve sfely, plese note the following points: 3/2-wy directionl poppet vlves hve negtive overlp. his mens tht during shift, some lekge occurs s ports, nd re connected together. his process occurs rpidly nd is not concern in most pplictions. When using the se plte (4/2-wy function) the following vlues must e complied with p min = 6 SI (8 r), q V > 0.8 GM (3 L/min). orts,, nd re rrnged ccording to function. hey must not e plugged or used in ny other mnner! ort must e connected to tnk. y ttention to pressure peks nd pressure distriution! Flow is only permissile in the direction of the rrow! he mximum flow must not e exceeded (if necessry, use n orifice insert to limit flow)! Orifice insert Crtridge check vlve insert o limit mximum flow, orifice inserts re optionlly ville. he orifice insert is required when, due to operting conditions during switching, flow rtes occur tht exceed the performnce limits of the vlve. For this purpose, the insert instlls in ort. Exmples: ccumultor circuits, ppliction s pilot vlve with internl pilot drin. 3/2-wy directionl poppet vlve he crtridge throttle is inserted in port of the poppet vlve. 4/2-wy directionl poppet vlve he crtridge throttle is inserted in port of the se plte. Crtridge check vlves llow free flow from to nd provide lekfree closure from to.
