Directionl Controls Model 4WEH Directionl vlves Model 4WEH... re solenoid pilot operted spool type vlves. In the stndrd version, 3-position spools re spring centered, while 2-position spools re hydruliclly offset. spring offset two-position, nd hydruliclly centered threeposition, option is lso ville for most sizes. Directionl control vlves control the strt, stop nd direction of fluid flow. 3-osition Vlves,Exmple 4WEH 22 E-7/6... In spring centered versions, the pilot vlve vents oth chmers (6) to tnk in center position. his llows return springs (3) to center spool (2) with respect to housing (). ilot vlve (4) is supplied vi pssge (7), either internlly from min port "" or externlly through pilot port "". When solenoid is energized, one of the two end cps (6) is pressurized, while the other is drined to tnk. Min spool (2) moves to shifted position, (flow pttern "" to "" nd "" to "" or "" to "" nd "" to ""), depending on which solenoid (5) is energized. lese refer to symols on pge 6, 7, nd 8 for exct flow ptterns/solenoid reltionships. ilot vlve (4) cn e internlly drined through min port "" or externlly drined through pilot port "". Mnul overrides re provided to operte the vlve without electriclly energizing the solenoid. For three-position vlves (except sizes nd 22), hydrulic centered option is ville (not shown). In this model, hydrulic centering requires oth end cp chmers (6) e pressurized in the non-energized condition. n "L" drin port (not shown) is provided through the min vlve interfce. 2-osition Vlves, Exmple 4WEH 22C7/6... In this model, the min spool (2) is normlly hydruliclly offset y 2-position pilot vlve (4). he end cp chmers (6) re supplied without springs (3). he pilot vlve my e 2-position, single solenoid (spool type "D"); 2-position, doule solenoid (spool type "D/O"); or doule solenoid with detent (spool type "D/OF"). lese refer to dt sheet R for dditionl informtion on the pilot vlve. spring offset, 2-position min spool (not shown) is lso ville. his option ssures the position of the min spool (2) during strt-up nd is prticulrly intended to e used with externlly piloted systems, where the min pumps re strted efore the pilot oil supply system. Directionl Controls Model 4WH...

During system design, plese consider the following: o chieve center position, the spring centered version requires venting oth end cp chmers (6). he pressure centered version requires pressuriztion of oth end cp chmers (6); nd two-position hydruliclly offset versions, spool (2) position cn only e ssured y mintining pilot pressure on either "" or port "". 2/22
