Product description：
The directional valve type WE is a solenoid-actuated directional spool valve. 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). When de-energized, the control spool (3) is held in the central position or in the initial position by the return springs (4) (except for version “O”). The control spool (3) is actuated by wet-pin electronic solenoids (2).
The force of electronic solenoid (2) acts via the plunger (5) on the control spool (3) and pushes the latter from its rest position to the required end position. This enables the necessary direction of flow from P to A and B to T or P to B and A to T.
When the electronic solenoid (2) is switched off, the return spring (4) pushes the control spool (3) back to its rest position.
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.

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 withoutdetent.
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 unintended
movements of the control spool if valves are equipped with a detent! We therefore recommend providing separate return lines or
installing a check valve in the tank line.
