Product description
The directional valves of type WE are solenoid-actuated directional spool valves that can be used as electro-hydraulic component. They control the start, stop and direction of a flow.
The directional valves basically consist of the housing (1), one or two electronic solenoids (2), the control spool (3), and the return springs (4).
In the de-energized condition, the control spool (3) is held in the central position or in the initial position by the return springs (4).
If the wet-pin electronic solenoid (2) is supplied with power, the control spool (3) moves out of its rest position into the required end position. In this way, the required direction of flow according to the selected symbol is released.
After the electronic solenoid (2) has been switched off, the control spool (3) is pushed back into its central position or into its initial position.
A manual override (5) allows for the manual switching of the valve without solenoid energization.
For unobjectionable functioning, the hydraulic system has to be bled properly.

Notices:
- The solenoid coils must not be painted.
- Actuation of the manual override is only possible up to a tank pressure of approx. 50 bar. Avoid damage to the bore of the manual override. (Special tool for the operation, separate order, material no. R900024943). When the manual override is blocked, the operation of the solenoid must be prevented.
- Any simultaneous actuation of 2 solenoids of one valve must be ruled out.
- You have to use connection cables that have been approved of for a working temperature of more than 105 °C.
- If the standard environmental conditions according to VDE 0580 cannot be provided, the valve must be especially protected.

Performance limits
(measured with HLP46, ϑOil = 40 ±5 °C)
Notice:
The specified performance limits are valid for operation with two directions of flow (e.g. from P to A and simultaneous return flow from B to T).
Due to the flow forces acting within the valves, the possible performance limit may be considerably lower with only one direction of flow (e.g. from P to A while port B is blocked).
The performance limits were determined when the solenoids were at operating temperature, at 10% undervoltage and without tank preloading.

Over-current fuse and switch-off voltage peaks
| Voltage data in the valve type code | Nominal voltage valve solenoid | Rated current valve solenoid | Rated current for external miniature fuse: Medium time-lag (M) according to DIN 41571 and EN/IEC 60127 |
| G24 | 24 VDC | 1.5 ADC | 1600 mA |
Notices:
Corresponding to the rated current, a fuse according to DIN 41571 and EN/IEC 60127 has to be connected upstream of every valve solenoid (max. 3 x Irated).
The shut-off threshold of the fuse has to match the prospective short-circuit current of the supply source.
The short-circuit current of the supply source to be expected may amount to a maximum of 1500 A.
