The Z4WE6E68-3X/EG24N9K4 valve belongs to the Z4WE Solenoid Actuation Spool Valves series from Bosch Rexroth and shifts hydraulic flow in automated circuits. It operates on a nominal voltage of 24 V DC, drawing a rated current of 1.25 A and consuming 30 W, so it can be powered directly from common control supplies. A continuous duty cycle of 100 % ED lets the coils stay energized without cool-down intervals, while the coil surface may reach 120 °C, which defines enclosure ventilation needs. A DIN EN 175301-803 connector with three pins plus protective earth offers a quick electrical interface, and the design withstands switch-off overvoltages up to 500 V to protect the winding insulation. The valve can perform up to 15 000 switching cycles per hour, supporting high-throughput hydraulic machinery.
The unit handles hydraulic flows up to 50 l/min and sustains 315 bar at ports P, A, and B, enabling control of medium-pressure actuators. Port T endures 210 bar in dynamic operation, preventing back-pressure damage to the return path. An ISO 4401-03-02-0-05 mounting pattern matches standard subplates, ensuring straightforward manifold integration. The housing carries an IP65 protection class, so it resists dust intrusion and low-pressure water jets. Fluid cleanliness must not exceed ISO 4406 code 20/18/15 to maintain spool and seal longevity. Installation is permissible in any orientation, granting layout flexibility, and the assembly weight of two solenoids is 1.6 kg, allowing manual handling during setup.
