4 Functionl,section Type 4WH... Type 4WEH Directionl vlves type 4WEH... Vlves of type WEH re directionl spool vlves with electrohydrulic opertion. They control the strt, stop nd direction of fluid flow. The directionl vlves siclly consist of the min vlve with housing (1), min control spool (2), one or two return springs (3.1) nd (3.2), nd the pilot vlve (4) with one or two solenoids "" (5.1) nd/or "" (5.2). The min control spool (2) in the min vlve is held in the neutrl or in the initil position either y the springs or y mens of pressure. In the initil position, the two spring chmers (6) nd (8) re connected to the tnk without pressure vi the pilot vlve (4). The pilot vlve is supplied with pilot fluid vi the pilot line. The pilot oil supply cn e either internl or externl (externl vi port X). When the pilot vlve is operted, e.g. solenoid "", the pilot spool (10) is shifted to the left nd thus spring chmer (8) is pressurized with pilot pressure. Spring chmer (6) remins un-pressurized. The pilot pressure cts on the left side of the min control spool (2) nd pushes it ginst the spring (3.1). As consequence, the ports P to B nd A to T re connected in the min vlve. When the solenoid is de-energized, the pilot spool returns to its initil position (exception: detented spool). The spring chmer (8) is unloded to tnk. The pilot oil is expelled from the spring chmer vi the pilot vlve into the Y chnnel. The pilot oil supply nd drin re internl or externl (externl vi port Y). An optionl mnul override (9) permits pilot spool (10) to e operted without energizing the solenoid. Directionl vlves type 4WH... Vlves of type WH re directionl spool vlves with hydrulic opertion. They control the strt, stop nd direction of fluid flow. The directionl vlves siclly consist of the vlve housing (1), the min control spool (2), one or two return springs (3. 1) nd (3.2) in the cse of vlves with spring return or spring centring, nd the pilot connecting plte (11). The control spool (2) is operted directly y mens hydrulic pressure. The control spool (2) is held in the neutrl or in the initil position either y springs or y mens of pressure. Pilot oil supply nd pilot oil drin re externl (see pge 2). 4/3-wy directionl vlve with spring centring of the control spool In this model, the min control spool (2) is held in the neutrl position y two return springs (3.1) nd (3.2). The two spring chmers (6) nd (8) re connected to ports X nd Y vi the connector plte (11). When one of the two ends of the min control spool (2) is pressurized with pilot pressure, the spool is moved to the shifted position. The required ports in the vlve re then opened to flow. When the pilot pressure is removed, the spring on the opposite side to the pressurized spool re cuses the spool to return to its neutrl or initil position. Hude Améric 4

5 Functionl,section Type 4WEH 16 H... 4/3-wy directionl vlve with pressure centring of the min control spool, type 4WEH H The min control spool (2) in the min vlve is held in the neutrl position y pressuriztion of the two front fces. A centring sleeve (12) is supported in the housing nd holds the spool in position. By removing the pressure from one of the spool ends, the min control spool (2) is moved to the shifted position. The unloded spool re displces the returning pilot oil vi the pilot vlve into the Y chnnel (externl). Hude Améric 5
