The 4WE6J6X/EG48N9DA/62 directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. It directs pressurized oil to actuators in hydraulic automation systems. A 48 V DC solenoid coil energizes the spool and draws a rated current of 0.66 A, providing predictable switching force from machine control circuits. The valve mounts on subplates conforming to ISO 4401-03-02-0-05, allowing quick replacement in standardized manifolds. During operation it passes up to 80 l/min of fluid, supporting medium-flow actuators without excessive pressure drop. The pressure chambers on ports P, A, and B withstand 350 bar, while the tank port tolerates 210 bar in direct-current operation, so the assembly suits high-pressure circuits. Cleanliness of the hydraulic medium must remain within ISO 4406 code 20/18/15 to prevent spool seizure and premature wear.
For service tasks the unit includes a concealed manual override that can be engaged when tank pressure stays below 50 bar, letting technicians shift the spool during power loss. Accurate positioning on the manifold is maintained by a locating hole and ISO 8752-3x8 pin, which stops lateral movement under pulsating loads. Reliable function is assured between ambient temperatures of ‑20 °C and +50 °C, matching typical mobile and factory installations. The hydraulic medium can range from ‑20 °C to +80 °C without affecting switching behavior, while the coil winding remains safe until its surface reaches 120 °C, preventing insulation breakdown during continuous duty. These limits, combined with the earlier flow and pressure ratings, define the valve’s working envelope for stable, long-term hydraulic control.
