Product description
Directional valves of type WE are solenoid-actuated directional spool valves. They control the start, stop and direction of a flow.
The directional valves basically consist of the housing (1), one or two solenoids (2), the control spool (3), and one or two return springs (4). In the de-energized condition, control spool (3) is held in the central position or in the initial position by the return springs (4). The control spool (3) is actuated by wet-pin solenoids (2).
To ensure proper functioning, make sure that the pressure chamber of the solenoid is filled with oil!
The force of the 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. In this way, the required direction of flow according to the symbol is released. After de-excitation of the solenoid (2), the return spring (4) pushes the control spool (3) back to its rest position.
The manual override (6) allows control spool (3) to be moved without solenoid energization.

| Important information on hydraulic fluids! For further information and data on the use of other hydraulic fluids, please refer to data sheet 90220 or contact us! There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.)! The flash point 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: When using bio-degradable hydraulic fluids that are zinc-solving, zinc may accumulate in the fluid (700 mg zinc per pole tube) | ||||
Notices!
- Only actuate the manual override using a rounded tool (Ø3+1 mm) or special tool (separate order, material no. R900024943)!
- Actuation of the manual override only up to a tank pressure 50 bar.
- When the manual override is blocked, the actuation of the solenoid must be prevented!
- The simultaneous actuation of the solenoids must be prevented!
In the electrical connection, the protective earthing conductor (PE, grounded) is to be connected in accordance with the stipulations.

Switching power limits (measured with HLP46, ϑOil = 40 ±5 °C)
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.
