The 4WE6D6X/OFEW110N9DALSO43A-1153-1 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is intended to route hydraulic flow in automated circuits. Its solenoid coil operates at a nominal 110 V AC on 50 or 60 Hz supplies, and the ±10 % voltage tolerance allows reliable shifting when line voltage varies. Coil current reaches 0.52 A at 50 Hz and 0.39 A at 60 Hz, parameters that help size control transformers and wiring. During energization, the coil draws 220 VA switch-on power for rapid spool movement, then stabilizes at 50 VA holding power to reduce heat and energy use. The design supports a 100 % duty cycle so the valve can remain energized continuously without premature coil fatigue. A maximum switching frequency of two actuations per second sets the upper limit for cyclic applications that require quick but repetitive flow changes.
The valve accommodates hydraulic flow rates up to 60 l/min while maintaining directional control, and it tolerates operating pressures of 350 bar on the pressure, A, and B ports for use in high-pressure systems. The tank port is limited to 160 bar, which must be observed when sizing return lines. Mounting follows the ISO 4401-03-02-0-05 (D03) porting pattern, enabling direct installation on common subplates. An IP65 enclosure rating shields the electrical elements against dust and low-pressure water jets, allowing placement in typical industrial environments. Coil insulation meets class H, letting the winding withstand surface temperatures up to 120 °C during prolonged service. A switch-off overvoltage ceiling of 500 V guides the selection of surge suppression devices when the coil is de-energized. Together these characteristics define electrical and hydraulic limits that ensure dependable valve performance in automated machinery.
