1 Diretionl spool vlve type WE eletrilly operted NS up to, M up to D SHEE - SERVICE MNU NUL dm /min WK LICION Diretionl spool vlves type WE eletrilly operted re intended for hnge in diretion of fluid flow in hydruli system nd thus it llows to hnge diretion of movement of reeiver - mostly piston rod of ylinder or hydruli motor s well to use funtions: on nd off. hese diretionl spool vlves re used for suplte mounting in ny pos in hydruli system. Diretionl spool vlve is omplied with the regultions of diretive 6/9/WE for the following voltges: V for C 7 V for DC DESCRIION OF OERION WE G -/GNZ Min elements of diretionl spool vlve type WE re: housing (), solenoids (), ontrol spool (), entering springs () nd mnul overrides (). he spool () is shifted when it is moved into one of end poss y the fore of solenoid () ffeting it. he return of the spool into neutrl pos nd entering re seured y the entering springs (). he shpe of the spool (ontrol edge sping) ffets the onfigurtion of onnetions mong the ports:,, nd. In se of emergeny, the spool n e shifted mnully y mens of the override () only for version with mnul override. When the sitution is ntiipted, diretionl spool vlve must e mounted in the wy s to e ville. 6 WE -/OF OF - only for spools:, C, D. wo-pos diretionl spool vlve without return springs with detent. he spool () is posed nd supported with detent (6), nd its shift results from supplying voltge to one solenoid (). ype WE - - WK 99 9.

It is foridden to pply diretionl spool vlve if the supply le in the glnd of plug-in in- onnetor is not properly tightened.. It is foridden to pply diretionl spool vlve if the plug-in in-onnetor is not proper operly tightened to the solenoid soket nd is not seured y srewing olt tightly tly.. Due to heting solenoid oils, diretionl spool vlves should e pled in order to eliminte the possiility of inidentl touh while using, or, they should e equipped with the oil overs (in ordne with the Eur stndrds N - EN ISO 7- nd N - EN 98).
