SUMMARY:  Directional spool valves: WE 10.-4x/

Add to Cart

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.

technical illustration-4WE10D4X/CG24N9DK23L-Directional spool valves: WE 10.-4x/

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 if valves are equipped with a detent! We therefore recommend providing separate return lines or

installing a check valve in the tank line.

3) Only with the use of the mating connectors indicated by us and with correct installation.
4) Due to the surface temperatures of the solenoid coils, the standards ISO 13732-1 and EN 982 need to be adhered to!

Notice!

Valve versions with electrical individual connection “K…” or central connection “DK…”, see Ordering code.

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 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 individual connection and a supply voltage of 12 V or 24 V can be operated with twice the voltage to reduce the switching time. For this purpose, the voltage has to be reduced to the nominal valve voltage after 100 ms by means of pulse width modulation. The maximum admissible switching frequency is 5 1/s. Due to possible overload of the board, valves with central connection must not be operated with twice the voltage.

 

Notice!

AC solenoids can be used for 2 or 3 mains; e. g. solenoid type W110 for: 110V, 50Hz; 110 V, 60Hz; 120V, 60Hz

In the electrical connection, the protective earthing conductor (PE, grounded) is to be connected in accordance with the stipulations.

For applications outside these parameters, please consult us!

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.
