4 4/10 Bosch Rexroth Oil Control S.p.A. LC1-DZ RE /12.13 Principles of opertion, cross section The sndwich plte design directionl vlve elements L511 re compct direct operted solenoid vlves which control the strt, the stop nd the direction of the oil flow. These elements siclly consist of stckle housing (1) with control spool (2), one or two solenoids (5), nd one or two return springs (4). When energized, the force of the solenoid (5) pushes the control spool (2) from its neutrl-centrl position 0 to the required end position or, nd the required flow from P to A (with B to T), or P to B (with A to T) is chieved. Once the solenoid is de-energized, the return spring (4) pushes the spool thrust wsher (3) ck ginst the housing nd the spool returns in its neutrl-centrl position. Ech coil is fstened to the solenoid tue y ring nut (6). A pin (7) llows to push the spool (2) in emergency conditions, when the solenoid cnnot e energized, like in cse of voltge shortge Technicl Dt (for pplictions with different specifictions consult us) Generl Vlve element with 2 solenoids kg [ls] 1.82 [4.0] Vlve element with 1 solenoid kg [ls] 1.33 [2.9] Vlve element with 2 solenoids, with lever type emergency Vlve element with 1 solenoid, with lever type emergency kg [ls] 2.1 [4.6] kg [ls] 1.6 [3.5] Amient Temperture C [ F] [ ] (NBR sels) Hydrulic Mximum pressure t P, A nd B ports r [psi] 310 [4500] Mximum pressure t T r [psi] 250 [3625] Mx pressure, with lever type emergency t T r [psi] 200 [2900] Mximum inlet flow l/min [gpm] 50 [13.2] Hydrulic fluid Generl properties: it must hve physicl luricting nd chemicl properties suitle for use in hydrulic systems such s, for exmple: Minerl oil sed hydrulic fluids HL (DIN prt 1).
