Z4WE6E68-30/EW110N9K4QMAG24

The Z4WE6E68-30/EW110N9K4QMAG24 valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for directing hydraulic flow in automated machinery. It supports a maximum flow of 60 l/min so the actuator group can cycle at moderate speeds without cavitation. The ports p, a, and b withstand up to 350 bar, while the tank line is limited to 160 bar, allowing the pressure stage to match standard high-pressure systems yet protect the return path. An ISO 4401-03-02-0-05 porting pattern lets the unit bolt onto NG06 manifolds without adapters. The solenoid can remain energized continuously thanks to a 100 % duty cycle, which suits repetitive production tasks. Initial energization draws 220 VA, then the coil settles to a 50 VA holding level to reduce heat and power consumption once the spool is shifted. A nominal rating of 110 V AC at 50/60 Hz covers common plant mains, and a ±10 % voltage tolerance maintains performance during supply fluctuations. Operation requires a rectifier, converting the supply to DC to stabilize the magnetic field during sustained actuation.

A DIN EN 175301-803 K4 connector provides a keyed, vibration-resistant electrical interface that speeds coil replacement in the field. The enclosure achieves an IP65 protection class, preventing dust ingress and water jets from affecting the solenoid when the machine is washed down. A concealed manual override identified by code N9 permits local shifting without energizing the coil, and the override path tolerates up to 50 bar back-pressure so maintenance personnel can test circuits under load. A QM position switch monitors spool “a” and outputs a 24 V DC signal for feedback into the machine control, enabling fault detection if the valve fails to reach its commanded state. With these connection, protection, and diagnostic features, the valve integrates safely into modern hydraulic automation platforms.
