1 4/ nd 4/3 Solenoid Directionl Vlve, ISO Size 03 Q mx = 60 l/min, p mx = 315 r wo-stge design, with EX-sfty solenoid coil Vlve: High switching relilility thnks to two-stge follower spool design Slip-on coil design, coils cn e chnged without opening hydrulic envelope With mnul override Interfce to ISO Solenoid coil: o EN , EN , EN o EN , EN Certificte of conformity: 00 EX 11 X 1 Description gs: dust: II G Ex em II 4 II D Ex td 1 ( C) Series EEX-WEV...-6 high performnce spool vlves re two-stge units which use the follower spool principle. he min vlve components re steel ody, spring-centered follower spool ssemly nd wet rmture solenoids with pressure-tight core tue nd slip-on coil which is certified for use in explosion-hzrd res. he coil slips over the core tue nd is retined y knurled nut. he solenoid housing is mde of luminium with spry pinted finish. he solenoid rmture is of the oil-immersed type. he coil winding is vcuum encpsulted nd s result hs high opertionl reliility. he coil terminl ox is threded G 13,5 for cle entry glnd. Vlves re supplied complete with cle entry glnd ut without cle. he vlves provide relile service even under the severest operting conditions such s high flow rtes, high operting pressures, long periods without switching nd lrge temperture fluctutions. he highly effective spool ctution method comines the dvntges of oth direct cting nd two-stge solenoid vlves, without incurring the well known disdvntges of either type. he min spool is offset y oth the solenoid force nd the - *) pressure difference inside the vlve. he greter the - pressure difference, the gre-ter the offsetting force. It is rought ck to its deenergised position in the sme wy, using the - pressure difference nd without the need for hevy centering springs. *) he pressure in must exceed tht in nd the vlve must e connected in the conventionl mnner i.e. presssure to, to tnk.
