The 4WE6D6X/OFEW110N9DA/62SO43A-1153-1 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and routes hydraulic oil in automated machinery. It conforms to size 6 dimensions and mounts on an NFPA D03 interface, with ports arranged to the ISO 4401-03-02-0-05 pattern for straightforward manifold interchange. An electromagnetic coil designed for a nominal 110 V AC at 50/60 Hz actuates the spool and tolerates a ±10 % supply variation. The coil draws 220 VA at switch-on, then drops to 50 VA holding power to reduce energy use. Continuous energization is permitted by a 100 % ED duty cycle, while insulation class H and a 120 °C maximum coil surface temperature keep thermal stresses within safe limits. NBR sealing elements prevent external leakage when the valve is used with common mineral oil media.
The hydraulic end accommodates demanding circuit conditions. Ports A, B, and P sustain operating pressures up to 350 bar, giving the valve the headroom needed for high-pressure actuation tasks. When driven by AC power, the unit passes up to 60 l/min, whereas DC operation raises the flow capability to 80 l/min for faster cylinder or motor response. Back-pressure limits at the tank port differ by excitation type: 160 bar with AC coils and 210 bar with DC coils. These ratings allow the spool to shift reliably under varying return-line conditions and help maintain seal integrity throughout continuous duty cycles.
