LICION Electriclly controlled directionl control poppet vlve type UREZ6 is intended for chnging the direction of hydrulic fluid flow in system, which llows for chnge of the direction of the receiver motion - usully piston rod of cylinder or hydrulic motor, s well s performnce of modes strt, stop. It is suitle for suplte mounting in ny position in hydrulic systems. he product is complied with the regultions of directive 006/95/WE for the following voltges: 50 50 V for C 75 50 V for DC DESCRIION OF OERION Electriclly controlled directionl control poppet vlve type UREZ6 NS6 up to 5 M up to 0 D SHEE - OERION MNUL version 4UREZ6 version UREZ6 dm /min WK 4 770 10.015 UREZ6 D1-1/15 G4 N Z4 6 4 1 5 7 8 Min elements of the UREZ6 type vlve include: ody (1) with vlve sets () nd (), spool with closing poppet (4), solenoid (5), spring (6) nd mnul override switch (7). oth chmers from the side of the spring (6) nd solenoid (5) re y the design of the ody (1) nd the spool (4) connected to port nd shut off from port in order to lnce the forces ffecting the spool (4). his llows the flow in specific directions (in ccordnce to the digrms on pge 4) t the mx. working pressure in ech of the ports. he -wy version of the vlve UREZ6 cn e mnufctured s closed in neutrl (current-free) position - version UREZ6D1 (shown on the drwing) or open - version UREZ6D, depending on the ody (1) side where the solenoid (5) nd spring (6) re instlled. In the version shown on the drwing, in neutrl position the poppet of the spool (4) is pressed y the spring (6) to the vlve set (). ort remins shut-off, the flow from to is open. Override of the vlve is performed y moving the spool (4) y the solenoid (5) to the opposite end position, where the poppet of the spool (4) is pressed to the port () llowing to open the flow from to nd shutting off port. Return to the initil (neutrl) position is forced y the spring (6), In cse of power outge, it is possile to perform mnul override of the vlve y the utton (7). In the -wy version, port of the vlve is mnufctured s lind hole, fter shutting of the connection, the vlve cn ct s -wy vlve. When connected to n dditionl sndwich type suplte (9), the -wy directionl vlve cn e used s 4-wy - version 4UREZ6 (description of opertion on pge ).
