MATERIAL:  R901392681

SUMMARY:  

Add to Cart

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.

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.

technical illustration-R901392681-

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 100 ms 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. 3 mm.

Important information on hydraulic fluids:

For further information and data on the use of other hydraulic fluids, please refer to the data sheets above or contact us. There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.). The ignition temperature of the hydraulic fluid used must be 40 K higher than the maximum solenoid surface temperature.

Flame-resistant – containing water:

Maximum pressure differential per control edge 50 bar. Pressure pre-loading at the tank port >20% of the pressure differential; otherwise, increased cavitation Life cycle compared to operation with mineral oil HL, HLP 50 to 100 %

Bio-degradable and flame-resistant: When using hydraulic fluids that are simultaneously zinc-solving, zinc may accumulate (700 mg  zinc per pole tube).

1) Only possible with rectifier. Mating connectors with rectifier (separate order). For possible voltages, see ordering code. Rectifiers must comply with the relevant standards as well as the coil performance data!
2) Reduction of the nominal power by approx. 40 % when using a 24 V coil with connector switching amplifier type VT-SSBA1-PWM-1X/V002/5 (separate order, material no. R901265633, see data sheet 30362)
3) Operating mode according to VDE 0580
4) Measured with flow, 80 % performance limit and horizontal installation position. Not with symbols A and B. Reduction of the switching time by approx. 50 % when using a 12 V coil with connector switching amplifier type VT-SSBA1-PWM-1X/V001/5 (separate order, material no. R901265633, see data sheet 30362)
5) Measured with flow, 80% performance limit and horizontal installation position.
6) Measured without flow
7) Surface temperature > 50 °C, provide contact protection.

Notes!

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 single connection and supply voltage 12 V or 24 V 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 100 ms by means of pulse width modulation. The maximum admissible switching frequency is 5 1 /s. If the standard environmental conditions according to VDE 0580 cannot be provided, the valve must be especially protected!

Notice!

The specified switching power 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 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!

The switching power limit was established while the solenoids were at operating temperature, at 10 % undervoltage and without tank preloading.

1) Interference protection circuit integrated
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.
