The 4WE6J6X/EW440N9DA/62 valve is produced by Bosch Rexroth for the WE Directional Spool Valves series to shift hydraulic flow paths in automation systems. It is built to the ISO 4401-03-02-0-05 (NFPA D03) porting pattern so it fits standard subplates. Nominal size 6 keeps the envelope compact for manifolds with limited space. A wet-pin solenoid, coded E, bathes the armature in oil to improve damping and service life. Switch-on power of 220 VA delivers the initial force needed to move the spool, while holding power falls to 50 VA to minimize coil heating. The coil remains within a 120 °C maximum surface temperature to protect insulation, and a 100 % ED duty cycle allows uninterrupted energization without thermal derating. Voltage tolerance of ±10 % lets the solenoid function reliably despite supply fluctuation.
The valve passes up to 60 l/min, giving adequate flow for medium-size actuators. Ports A, B, and P withstand 350 bar so the unit can operate in high-pressure circuits, and port T is limited to 160 bar to safeguard the tank return line. Mounting screws must be tightened to 7 Nm to secure the body and maintain seal integrity. Alignment on the subplate is assisted by the locating hole and pin designation /62, reducing installation error. A concealed manual override, coded N9, enables emergency actuation while remaining protected against accidental use, and the override is rated for tank pressures up to 50 bar to ensure leak-free operation during depressurization.
