4WE6EB6X/EG24K4QM0G24

The 4WE6EB6X/EG24K4QM0G24 valve is manufactured by Bosch Rexroth as part of the WE Directional Spool Valves series. It directs hydraulic flow between ports in industrial automation circuits to start, stop, or reverse actuators. The valve follows the ISO 4401-03-02-0-05 porting pattern, so it bolts to standard subplates without adapter blocks. An NFPA T3.5.1 D03 interface further ensures compatibility with North American mounting patterns. Channels a, b, and p withstand operating pressures up to 350 bar, while return port T is limited to 210 bar, allowing the unit to manage high-pressure supply lines yet protect tank connections. Continuous flow up to 80 l/min can be routed through the spool without exceeding rated pressure drop. Hydraulic cleanliness must reach ISO 4406 class 20/18/15 to avoid accelerated wear of critical edges. A cast housing with an IP65 enclosure rating blocks dust and low-pressure water jets during field installation, and the assembly with two solenoids weighs 1.95 kg for straightforward manifold mounting.

Electrical actuation is provided by a 24 VDC solenoid coil that draws 1.25 A under nominal conditions and consumes 30 W, delivering consistent magnetic force across the rated stroke. The coil is designed for a 100 % duty cycle (S1) so it can remain energized indefinitely without thermal cycling. Surface temperature is permitted to rise to 120 °C, enabling operation in warm cabinets while staying within insulation limits. The K4 connector in accordance with DIN EN 175301-803 provides quick plug-in power wiring and supports field replacement. Spool shifts can occur at a maximum frequency of 4.2 cycles per second, which permits rapid response in servo-assisted machinery. A QM0 position switch rated for 24 V monitors the rest position to transmit feedback to the control system. Together these electrical features integrate the valve into automated hydraulic controls that demand reliable, repeatable switching performance.
