The Z4WE6E68-3X/EG24K4QMAG24 solenoid-actuated spool valve belongs to the Z4WE Solenoid Actuation Spool Valves series and is manufactured by Bosch Rexroth for directional control in hydraulic automation systems. It is built in size 6 and uses an ISO 4401-03-02-0-05 porting pattern, making it compatible with standard subplates. The hydraulic section carries a maximum flow rate of 50 l/min, and ports p, a, and b withstand pressures up to 315 bar while the tank and drain ports are limited to 210 bar. The solenoid operates from a 24 V DC supply, draws 1.25 A, and consumes 30 W, which allows direct connection to common machine power buses. A 100 % ED (S1) duty cycle lets the coil remain energized continuously without overheating, enabling uninterrupted valve actuation during prolonged machine cycles.
The unit offers an Mttfd of 150 years, providing a very low probability of dangerous failure over its service life. An IP65 ingress protection rating shields the coil and terminals from dust and low-pressure water when the DIN EN 175301-803 three-pole connector with protective earth is properly installed. The coil surface can reach 120 °C without damaging insulation, supporting use near hot hydraulic reservoirs. A switching frequency of up to 15 000 cycles per hour permits rapid direction changes in high-response circuits. Fluid cleanliness must meet ISO 4406 20/18/15 to protect the precision spool and bore. Spool position monitoring option “a” supplies feedback to the control system, confirming that commanded shifts have been completed.
