The Bosch Rexroth 4WE6H7X/HG24N9K4 (R901130745) is a high-performance industrial hydraulic valve designed for subplate mounting with a size 6 CETOP D interface, conforming to NFPA T3.5.1 R2 D03 and ISO 4401 standards. This direct-actuated spool valve, featuring the H spool symbol, is engineered to reliably switch the direction of oil flow in hydraulic systems. It is equipped with wet-pin solenoids for actuation and has a maximum operating pressure capability, ensuring it can handle demanding applications.
The valve's solenoid actuation allows for precise control over the start, stop, and direction of flow with multiple switching positions available. The solenoids are designed to be energized by a supply voltage of 24 VDC and are connected via a connector pole PE according to EN 175301-803 standards. Additionally, the valve boasts an impressive maximum flow rate.
For maintenance and emergency handling, the 4WE6H7X/HG24N9K4 includes a manual override feature that permits manual operation without solenoid energization. Its robust design incorporates NBR seals compatible with several types of hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC.
This Bosch Rexroth directional spool valve is characterized by its durable construction and reliable performance in controlling hydraulic functions across various applications. The combination of its technical specifications ensures that it can meet the requirements of medium-range performance tasks while delivering consistent operational excellence.

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.

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.
