Rexroth 4WE10J 4WE10J3X 4WE10J31B 4WE10JA3X/CW110N9K4 Hydraulic Directional Control Solenoid Valve

Directional valves type WE are solenoid operated directional spool valves. They are used to control the start, stop and direction of a flow. The directional valves basically comprise of the housing (1), one or two solenoids (2), a control spool (3), and one or two return springs (4). In the de-energised condition the control spool (3) is held in its central or initial position be means of the return springs (4) (with the exception of impulse spools). The control spool (3) is operated by the wet pin solenoids (2).In order to ensure correct function care must be taken that the solenoid pressure chamber is filled with oil. The force of solenoid (2) acts on the control spool (3) and moves it from its initial position to the desired end position. This permits free flow from P to A and B to T or P to B and A to T. On de-energising the solenoid (2) the control spool (3) is returned to its initial position by the return spring (4). The optional hand override (5) permits the control spool (3) to be moved without the solenoids being energised.

Type .WE 10.3X/OC.... (only possible with symbols A, C and D) This model is a 2-position directional valve with 2 solenoids without detents. The spool position, when the solenoids are de-energised, is not defined

Type .WE 10.3X/OFC... (impulse spool), with detent (only possible with symbols A, C and D) This model is a 2-position directional valve with 2 solenoids and detents. Hence, when the solenoids are de-energised, the spool is held in the detented position and thus the solenoids do not need to be continuously energised.

Cartridge throttle (type 4WE 10…/.../B..) A cartridge throttle is required when, if due to the operating conditions, flows can occur during the switching procedure which are higher than the permitted performance limits of the valve. The throttle is inserted into the P port of the directional valve.
