The 4WE6D6X/EG24N9K72LQMAG24 valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and directs hydraulic flow in automated machinery. The solenoid coil works from a nominal 24 V DC supply so it can be powered directly from common control units, while its 30 W nominal power delivers the magnetic force required to shift the spool. A rated current of 1.25 A at that voltage helps designers select suitable drivers and conductors. Continuous energization is possible because the duty cycle is 100 % ED (S1), eliminating the need for intermittent operation. The unit can cycle up to 4.2 times per second, which supports high-speed motion sequences. Hydraulic throughput reaches 80 l/min under direct-current actuation, and ports P, A, and B withstand pressures to 350 bar for use in high-pressure circuits. Mounting follows the ISO 4401-03-02-0-05 porting pattern, and fluid cleanliness must stay within ISO 4406 code 20/18/15 to avoid wear.
The electrical interface is a 4-pole M12×1 connector labeled K72L, enabling quick installation with standardized pinouts. An IP65 ingress rating keeps dust and low-pressure water jets out of the enclosure so the valve may operate in wash-down areas. A concealed manual override designated N9 lets technicians shift the spool during commissioning, and it can be used while the tank line remains below 50 bar. The tank port itself tolerates continuous return pressure up to 210 bar, allowing the valve to sit downstream of restrictive components. An inductive QM position sensor tracks spool location and is powered from a separate 24 V DC supply, providing non-contact feedback for monitoring systems. These auxiliary features bring reliable electrical connection, environmental sealing, manual control, back-pressure capability, and position feedback without increasing the footprint.
