The 4WE6G6X/EW230N9K4/ZV directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs pressurized hydraulic fluid between actuators and the tank. It is built to the NG6 nominal size so it mates with subplates that follow the ISO 4401-03-02-0-05 pattern. A maximum operating pressure of 350 bar at ports A, B, and P supports high-pressure circuits, while a maximum flow of 60 l/min sets the throughput limit for stable motion control. The solenoid coil accepts 230 V AC at 50/60 Hz; it draws 220 VA at switch-on and falls to 50 VA during the holding phase, with a rated current of 0.23 A at 50 Hz. Continuous energization is possible because the duty cycle is 100 % ED, allowing the valve to remain shifted without thermal interruption.
A clamping length of 22 mm positions the body securely against the manifold face, and the K4 electrical connector specified by DIN EN 175301-803 simplifies wiring in control cabinets. A concealed N9 manual override lets maintenance staff move the spool mechanically while protecting it from accidental use in service. The IP65 ingress protection rating keeps dust and low-pressure water jets out of the enclosure, maintaining coil integrity in wash-down zones. FKM seals resist common hydraulic oils and elevated temperatures, extending service life. The tank port is rated for 160 bar, so return-line restrictions can be accommodated without exceeding seal limits.
