The 4WE6HA6X/EG24N9K4QM0G24 valve belongs to the WE Directional Spool Valves series manufactured by Bosch Rexroth to route pressure fluid in automated hydraulic manifolds. It withstands a maximum operating pressure of 350 bar at the pressure and service ports, while the tank port tolerates up to 210 bar during direct-current actuation. An 80 l/min flow rating supports medium flow circuits, and the ISO 4401-03-02-0-05 (D03) porting pattern lets the body bolt directly to standard subplates. Electrical control is provided by a 24 V DC solenoid that accepts a ±10 % voltage swing and draws 30 W during steady load; continuous energization is permitted because the duty cycle is 100 % ED.
The valve uses a K4 plug according to DIN EN 175301-803, and the assembly reaches IP65 when the connector is properly sealed. Spool position monitoring is available in the QM0 rest state with a 24 V DC feedback line for supervisory circuits. Coil insulation is protected against up to 500 V switch-off overvoltage, and the winding surface may rise to 120 °C without degradation. Reliability is indicated by an MTTFd of 300 years under EN ISO 13849. Fluid cleanliness must be held at 20/18/15 under ISO 4406 to prevent sticking and wear.
