The 4WE6X12-6X/EG24N9K4/ZV valve belongs to the WE Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation systems that require reliable flow direction control. It fits the NG6 size and engages a subplate through the ISO 4401-03-02-0-05 interface so installers can swap units without redrilling manifolds. A clamping length of 22 mm secures the housing to the subplate, while a wet-pin, high-power solenoid supplies the force needed to shift the spool under full pressure. The coil is rated for 24 V DC and draws 1.25 A, a combination that matches common machine control voltages. Electrical termination uses the K4 plug to DIN EN 175301-803, and when that connector is fitted the assembly reaches IP65, shielding the coil from dust and splashed fluids. FKM seals are used throughout the pressure zones to withstand mineral oil and elevated temperatures in industrial circuits.
Four main ports permit conventional P, T, A, B routing, and the design passes up to 80 l/min of flow in direct current service. Pressures of up to 350 bar are accepted on the pressure and work ports, while the tank port endures 210 bar during dynamic duty. A concealed manual override (N9) lets maintenance staff shift the spool without voltage; its use is limited to circuits where tank pressure stays below 50 bar. A throttle insert at port T with a 1.2 mm orifice (X12) moderates return flow and cushions spool movement, enhancing stability in sensitive actuators. These features combine to give the valve consistent switching performance and adaptability across medium-pressure hydraulic machinery.
