The Bosch Rexroth 3WE6A7X/HG12N9K4 (R901089276) is a high-performance industrial hydraulic valve designed for reliable operation and efficient control of oil flow direction. This direct-actuated spool valve features a spool symbol A, indicating its specific flow pattern, and is suitable for subplate mounting with a connection diagram that complies with NFPA T.3.5.1 R2 D03 and ISO 4401 standards. The valve operates with a maximum pressure capacity and is equipped with an electrical connection featuring a connector pole PE according to EN standards.
With solenoid actuation, the 3WE6A7X/HG12N9K4 valve has a size designation of CETOP D03 and can manage a substantial max flow rate. It offers versatility through its multiple ports and switching positions, making it applicable in various hydraulic systems requiring precise control. The solenoid coils are wet-pin type, which can be rotated for ease of installation, and the coil can be replaced without opening the pressure-tight chamber.
This Bosch Rexroth valve ensures reliability with its robust NBR seals compatible with a range of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, and HFC types. The manual override feature allows operators to move the control spool without solenoid energization for added operational flexibility.
Built to deliver consistent performance under demanding conditions, this directional spool valve is an essential component in hydraulic applications where start-stop functions and directional flow control are critical. The unit's design facilitates easy maintenance while ensuring long service life and operational safety. Its supply voltage requirement is 24 VDC and it has been engineered to withstand substantial operational pressures up to the maximum specified limit while maintaining optimal flow rates within hydraulic circuits.

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.
