2 RE 9 /9.95 Functionl description, section ilot vlve type DRE 6... he pilot vlve is proportionl solenoid operted -wy pressure control vlve. It is used to convert n electricl input signl into proportionl pressure output signl nd is used on ll WRZ... nd 5WRZ... type vlves. he proportionl solenoids re controllle DC wet pin solenoids. hey convert n electricl current proportionlly into mechnicl force. Incresing the current intensity cuses corresponding increse in their solenoid force. he set solenoid force remins constnt over the entire control stroke. he pilot vlve consists siclly of housing (), two pressure mesuring spools (5; 6) nd two proportionl solenoids (; ). In the de-energised condition the control spool () is held in the centre position y the return springs. he control spool () is directly operted y the proportionl solenoids ( or ). If solenoid () is energised, its force cts vi the pressure mesuring spool (5) on the control spool () nd pushes it to the right, therey llowing pressure fluid to flow from to. he pressure which is uilding up in port cts vi the rdil drillings in the control spool () on the pressure mesuring spools (6). he resulting pressure force cts ginst the solenoid nd pushes the control spool () towrds its closing position until the two forces re gin in lnce.he pressure mesuring spool (6) supports itself on the pin of solenoid (). t this point the connection from to is closed, the pressure in service port is held constnt. reduction in the solenoid force leds to n excess in force on the control spool (). his cuses the spool to move to the left. he pressure fluid cn flow vi the connection from to nd the pressure reduces ccordingly. gin, force lncing mens holding the pressure constnt, however, now t the lower level. In the neutrl position - proportionl solenoids de-energised - the connections nd re open, llowing the pressure fluid to flow unhindered ck to the reservoir. t the sme time the connection to nd to is closed.

Vlve types WRZ... re pilot operted -wy vlves operted y mens of proportionl solenoids. hey control the direction nd flow rte of hydrulic fluid. hese vlves consist siclly of the pilot vlve (9) with its two proportionl solenoids ( nd 6), the min vlve () together with the min spool () nd centering spring (5). In the non-operted condition the centering spring (5) holds the min spool () in the centre position. If "" (6) is energised, it moves the control spool () to the right. ilot oil is then either fed "internlly" from line or "externlly" vi port into the pressure chmer () vi the pilot vlve (9) nd moves the min spool () distnce proportionl to the strength of the electric current. he throttling grooves in the min spool () open progressively with incresing current, thus controlling the flow of hydrulic fluid to the ctutor ports. When the solenoid current is switched off the control spool () nd lso the min spool () re returned to their neutrl position, regrdless of the control pressure. n emergency hnd opertor ( nd, optionl) permits movement of the pilot spool () without energising the solenoid. RE 9 /9.95 Size 5 su-plte mounting 5-wy vlves re fitted with n dditionl "R" port. Depending on the spool position, fluid flows from to nd to or to nd to R. Note! In order to chieve the optimum functioning of the vlve, the vlve must e led t the commissioning stge: Supply pressure to vlve, remove screws t 7 nd 8, nd top up with hydrulic fluid s required, when no further ules exit screw in items 7 nd 8.
