The 5-chamber directional valve type 5-.WE is a solenoid-actuated directional spool valve with switching time increase. 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 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 valves without spring "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 the central position or in the initial position (except for valve with "OF" detent and valve without spring type "O").
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.
Type 5-4WE 10 …
Throttle insert
Using a throttle insert (9) 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 unintended 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.
Influencing the switching time
With the 5-chamber directional valve type 5-.WE, the switching time can be delayed to 100ms and more by means of a throttle screw "C" (7) or a selected orifice "A0.” (8). In this connection, the switching time is pressure-, flow- and viscosity-dependent, specific to the installation. The switching time is influenced by means of a restriction (throttle or orifice) in the connection channel (5) between the two spring chambers in which the liquid volume is displaced from one spring chamber into the other in case of a switching process.
The T channels are separated from the spring chambers in order to achieve soft switching.
Notices!
The adjustment spindle (10) may only be screwed out so that it protrudes from the nut by max. 3mm.

Notes!
The solenoid coils must not be painted. Actuation of the manual override is only possible up to a tank pressure of approx. 50bar. Avoid damage to the bore of the manual override! (Special tool for actuation, separate order, material no. R900024943). When the manual override is blocked, actuation of the opposite solenoid must be ruled out! The simultaneous actuation of 2 solenoids of one valve must be ruled out! Use cables that are approved for a working temperature above 105°C. When solenoid coils are switched off, voltage peaks result which may cause faults or damage in the connected control electronics. The user has to provide for a suitable circuit for limiting the voltage peaks. It must be noted that a diode switched in an antiparallel form extends the switching off time. Valves with single connection and supply voltage 12V or 24V can be operated with twice the voltage for reducing the switching time. For this purpose, the voltage has to be reduced to the nominal valve voltage after 100ms by means of pulse width modulation. The maximum admissible switching frequency is 51/s. If the standard environmental conditions according to VDE 0580 cannot be provided, the valve must be especially protected!

Due to the flow forces acting within the valves, the admissible switching power limits 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!

| 2) | To be ensured by user circuitry |
Notice:
When solenoid coils are switched off, voltage peaks result which may cause faults or damage in the connected control electronics. We therefore recommend limiting them to 2 x nominal voltage by means of an interference protection circuit. It must be noted that a diode switched in an antiparallel form extends the switching off time.
