The Z4WE6E63-3X/EG24N9K4QMBG24 belongs to the Z4WE Solenoid Actuation Spool Valves series produced by Bosch Rexroth for directional control in hydraulic automation. It is built around nominal size 6 passages that accommodate a maximum flow of 50 l/min so cylinders and motors receive adequate oil volume. A standardized ISO 4401-03-02-0-05 porting pattern simplifies manifold mounting and interchange with other size-matched components. The coil operates on a nominal voltage of 24 V DC and draws a rated current of 1.25 A, resulting in a direct-current power demand of 30 W. Continuous service is possible because the electromagnetic assembly is specified for a 100 % duty cycle. Environmental sealing reaches IP65, preventing dust ingress and low-pressure water jets from affecting the valve during field installation.
A concealed manual override permits local actuation without disturbing the electrical interface, which is wired through a DIN EN 175301-803 three-pole connector. Hydraulic ports p, a, and b withstand operating pressures up to 315 bar, while the return line t and drain Dc are limited to 210 bar, allowing the designer to match line ratings to each function. The coil survives switch-off transients up to 500 V, protecting upstream drivers from inductive spikes, and the magnet system supports 15 000 switching cycles per hour for rapid sequencing. Spool position is monitored in position b to confirm commanded states via external sensors. A calculated mean time to dangerous failure of 150 years reflects the mechanical and electrical reliability expected in safety-related circuits.
