The Bosch Rexroth 4WE6D7X/HG24N9K4/V/62 (R901321390) is a high-performance directional spool valve designed for controlling the start, stop, and direction of fluid flow within a hydraulic system. This solenoid-actuated valve is built with precision engineering to ensure reliability and durability. It features a robust housing, one or two solenoids depending on the application, a control spool, and return springs. In its default state, the control spool is held in either a central or initial position by the return springs. The valve operates using wet-pin solenoids which require an oil-filled pressure chamber for proper functionality. The solenoid force is transferred through a plunger to the control spool, moving it from its rest position to an end position that allows fluid flow in the desired direction as indicated by the symbol. When the solenoid is de-energized, the return spring moves the control spool back to its resting state. An additional feature of this model includes a manual override that permits movement of the control spool without electrical power to the solenoids. This function provides an extra layer of operational flexibility and safety. The 4WE6D7X/HG24N9K4/V/62 valve conforms to DIN standards with porting pattern form A and incorporates wet-pin DC solenoids that can be rotated for ease of installation and maintenance. Furthermore, it allows for coil replacement without opening the pressure-tight chamber, ensuring minimal downtime during service operations. The electrical connections are designed for individual connections with concealed manual overrides. This model comes in size 6 with component series X marking, capable of handling maximum operating pressures up to bar and maximum flow rates measured in liters per minute (l/min), making it suitable for various hydraulic applications that demand precise control over fluid dynamics.

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.
