4WE6D6X/EW110N9K4QMAG24

The 4WE6D6X/EW110N9K4QMAG24 is a directional spool valve produced by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow in automation circuits by shifting a spool in response to a 110 V AC coil, enabling precise actuation of cylinders and motors. The valve bolts to manifolds through the ISO 4401-03-02-0-05 mounting interface, so installation remains consistent with CETOP 03 patterns. Hydraulic ports A and B tolerate pressures up to 350 bar, allowing use in high-pressure systems, while the tank port rating of 160 bar supports reliable return flow. When energized, the solenoid draws 220 VA at switch-on to overcome static friction, then settles to a holding demand of 50 VA to reduce heat and energy consumption. Continuous service is supported by a 100 % ED duty cycle, so the coil can remain energized without mandatory cooling periods. The core cross section permits a maximum flow rate of 60 l/min, matching medium-size actuator requirements.

Electrical termination is provided through a DIN EN 175301-803 connector coded K4, which simplifies field wiring and matches standard cable glands. With an IP65 protection class for this connector, the assembly resists dust ingress and low-pressure water jets found in industrial wash-down zones. Under continuous excitation the coil surface may reach 120 °C, so users must ensure ambient temperatures and wire insulation accommodate that level. A concealed manual override identified as type N9 allows service technicians to shift the spool mechanically, and it can be used safely when tank pressure does not exceed 50 bar. For position feedback, the valve integrates a QM monitored-A limit switch that signals spool state to the control PLC. This switch operates on a 24 V DC supply, enabling direct connection to common sensor power buses without additional converters.
