1 WWMF1 Solenoid operted spool vlve with soft switching Flnge construction 4/3-wy with spring centred mid position 4/2-wy with spring reset Q mx = 12 l/min p mx = 35 r DESCRIION Direct operted solenoid spool vlve with 4 connections in 5 chmer design. With the solenoids deenergised, the spool is held in the center position y the spring (4/3), or switched ck to the offset position (4/2). he soft switching of the vlve is chieved y mens of n optimum comintion of the orifice nd spool design. recise spool fit, low lekge, long service life time. Spool mde from hrdened steel, ody from high qulity hydrulic cst steel. Wide rnge of stndrd nd specil voltges. NG1 ISO LICION Norml solenoid spool vlves switch very quickly. his cn led to shocks in the hydrulic system which cn cuse mechnicl wer nd hve negtive effect on opertion. he soft switching vlves slow down nd dmpen the switching movements which enefits the system. Optimum results cn e chieved if ll 4 connections re connected nd the vlve is properly vented.
