4WE6E13-6X/EG24N9K4

The 4WE6E13-6X/EG24N9K4 directional spool valve is produced by Bosch Rexroth in the WE Directional Spool Valves series and is intended to route hydraulic flow for automation tasks. A maximum operating pressure of 350 bar permits the valve to control high-pressure supply lines in heavy-duty actuators without loss of performance. Its maximum flow rating of 80 l/min provides sufficient volume for medium-size cylinders and motors. The ISO 4401-03-02-0-05 porting pattern matches common subplates so installation does not require custom manifolds. Compatibility with the NFPA T3.5.1 R2-2002 D03 mounting interface supports interchange with North-American stack systems. Operation on a 24 V DC supply keeps the coil wiring consistent with typical machine control voltages. A rated current of 1.25 A indicates the electrical load that must be budgeted for each energized solenoid. Nominal power of 30 W defines the heat generated during continuous actuation and informs cabinet ventilation sizing. The IP65 protection class seals the coil and connector against dust and low-pressure water jets for reliable service on open machinery.

A clamping length of 42 mm sets the stack height required for tie-rod fasteners on the manifold. The 100 % duty cycle lets the solenoid remain energized indefinitely during positioning sequences. Insulation class F protects the winding from thermal degradation when ambient or coil temperatures rise. A concealed manual override permits local shifting while preventing accidental actuation. The manual override can be used against tank pressures up to 50 bar, giving maintenance staff a clear limit for safe intervention. Tank port pressure is rated to 210 bar, ensuring return flow does not exceed spool seal capabilities. The coil surface temperature may reach 120 °C, so adjacent components must tolerate the elevated radiant heat. With two solenoids installed the valve weighs 1.95 kg, a figure relevant for support hardware and ergonomic handling.
