The directional valve type WE is a solenoid-actuated directional spool valve that can be used as electro-magnetic component. It controls the start, stop and direction of a flow.
The directional valve basically consists of housing (1), one or two electronic solenoids (2), 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) (except for version "O").
If the wet-pin electronic solenoid (2) is energized, 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 (except for valves with "OF" detent and valves without type "O" spring).
A manual override (6) allows for the manual switching of the valve without solenoid energization.
To ensure proper functioning, make sure that the pressure chamber of the solenoid is filled with oil.
For more functions, refer to the functional description.
Throttle insert "B.."
Using a throttle insert (7) in channels P, A, B or T, the flow resistance at the valve can be increased. Its use is required when, due to prevailing operating conditions, flows occur during the switching processes, which exceed the performance limit of the valve.
Without spring return “O” (only possible with symbols A, C and D)
This version is a directional valve with 2 spool positions and 2 electronic solenoids without detent. The valve without spring return at the control spool (3) does not have a defined basic position in the de-energized condition.
Without spring return with detent “OF” (only possible with symbols A, C and D)
This version is a directional valve with 2 spool positions and 2 electronic solenoids with detent. The detents are used to lock the control spool (3) in the relevant spool position. During operation, continuous application of current to the electronic solenoid can thus be omitted which contributes to energy-efficient operation.
Notice!
Pressure peaks in the tank line to two or several valves can result in unwanted movements of the control spool in the case of valves with detent! We therefore recommend that separate return lines be provided or a check valve installed in the tank line.

Notice:
The specified performance limits are valid for use 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 admissible performance limit may be considerably lower with only one direction of flow (e. g. from P to A while port B is blocked)!
In such use cases, please consult us!
The performance limit was determined when the solenoids were at operating temperature, at 10 % undervoltage and without tank preloading.

(measured with HLP46, ϑOil = 40 ±5 °C)
Notice:
The specified performance limits are valid for use 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 admissible performance limit may be considerably lower with only one direction of flow (e. g. from P to A while port B is blocked)!
In such use cases, please consult us!
The performance limit was determined when the solenoids were at operating temperature, at 10 % undervoltage and without tank preloading.
