In the de-energized condition, control spool (3) is held in the centrl position or in the initil position y the return springs (4) (except for impulse spool). Control spool (3) is ctuted y wet-pin solenoids (2). o ensure proper functioning, cre must e tken tht the pressure chmer of the solenoid is filled with oil. he force of solenoid (2) cts vi plunger (5) on control spool (3) nd pushes the ltter from its rest position to the required end position. his enles the necessry direction of flow from to nd to or to nd to. fter solenoid (2) ws de-energized, return spring (4) pushes control spool (3) gin ck to its rest position. n optionl mnul override (6) llows control spool (3) to e moved without energiztion of the solenoid. ype.we 6.. 6X/O... (only possile with symols, C nd D) his vrint is directionl vlve with two spool positions nd two solenoids without detent. In the de-energized condition, there is no defined spool position. ype.we 6.. 6X/OF... (impulse spool, only possile with symols C46 nd D46) his vrint is directionl vlve with two spool positions, two solenoids nd one detent. It lterntely locks the two spools in position nd the solenoid therefore needs not to e permnently energized. Note! ressure peks in the tnk line to two or severl vlves cn result in unwnted spool movements in the cse of vlves with detent! We therefore recommend tht seprte return lines e provided or check vlve instlled in the tnk line "" "" 4 4 () ype 4WE 6 E6X/.E SO407 hrottle insert he use of throttle insert is required when due to previling operting conditions, flows cn occur during the switching processes, which exceed the performnce limit of the vlve.
