1 Directionl spool vlve type URE electro-hydruliclly operted NS up to 35 M up to 6dm 3/min DAA SHEE - OERA RAION MANUA NUAL WK ALICAION Directionl spool vlves type URE electrohydruliclly operted re intended for chnge in direction of fluid flow in system nd thus it llows to chnge direction of movement of receiver - mostly piston rod of cylinder or hydrulic motor s well to use functions: on nd off. hese directionl spool vlves re used for suplte mounting in ny position in hydrulic system. he product is complint with the regultions of directive 24/35/UE. DESCRIION OF OERAION 4URE E 62/24 N Z A A B B Min ore nd nnulr ports,, A, B re mde in the housing () nd connected to its suplte connection. Directionl vlve is switched y shifting the spool (2) into one end position. Vrious control functions re dependent on the spool (2) which ffects the chnge in configurtion of connections mong ports,, A, B in the housing (). he spool (2) is shifted from its neutrl position y ffecting pressure of hydrulic fluid supplied vi pilot vlve (4) into one chmer of cps (3). he pilot vlve (4) - type WE6 is operted y mens of solenoids (5). he spool (2) is centered in neutrl position y mens of springs (7). In cse of filure, the pilot vlve (4) my e shifted mnully y mens of mnul overrides (6) - version URE / N. yp URE - - WK

2 DESCRIION OF OERAION 4URE.../...S.S... 4URE.../...- M Directionl spool vlve type URE cn e provided with the pilot choke djustment (8) nd/or spool position sensor (9). Accessories cn e mounted depending on version of directionl vlve like given on pges 2 to 7. INSALLAION AND OERAION REQUIREMENS. Only fully functionl nd opertionl directionl vlve, properly connected to electricl instlltion must e used. Connecting or disconnecting the directionl vlve to n electricl instlltion must only e crried out y qulified personnel. 2. round connection ( ) must e connected with protective erth wire (E ) in supply system ccording to pproprite instructions. 3. Solenoid plug shll precisely dhere to socket nd shll e secured with thred olt screwed in securely in plce. It is foridden to operte the directionl vlve if the tightness nd suitle clmp of cle in the plug glnd re not ensured. 4. During the period of opertion must e kept fluid viscosity cc. to requirements defined in this Dt Sheet - Opertion Mnul. 5. In order to ensure filure free nd sfe opertion the following must e checked: condition of the electricl connection proper working of the directionl vlve clenliness of the hydrulic fluid 6. Due to heting of solenoid coils to high temp., the directionl vlve shll e plced in such wy to eliminte the risk of ccidentl contct with solenoid during opertion or to pply suitle covers cc. to Europen stndrds: N - EN ISO nd N - EN In order to ensure tightness of the directionl vlve lock, one should tke cre of dimension of seling rings,, tightening torques nd vlve opertion prmeters given in this Dt Sheet - Opertion Mnul. 8. Any chnges, modifictions or djustments to the versions with M type spool position sensor cn e mde only y the producer - see notes on pge A person tht opertes the directionl vlve must e thoroughly fmilir with this Dt Sheet - Opertion Mnul.
