The 4WE6J6X/EW110N9K4/B10SO43A-1809 directional spool valve is produced by Bosch Rexroth in the WE Directional Spool Valves series for automated hydraulic flow control. Its nominal size of 6 allows compact installation on subplates that follow the ISO 4401-03-02-0-05 pattern. Compatibility with NFPA porting code T3.5.1 R2-2002 D03 aligns the valve with D03 manifolds widely used in North America. The solenoid coil is rated for 110 V AC at 50/60 Hz so it can be powered from standard industrial supplies, and a voltage tolerance of ±10 % keeps operation reliable during line fluctuations. Switch-on power peaks at 220 VA while holding power settles at 50 VA, values that guide power-supply and thermal design. Insulation class H according to VDE 0580 supports high winding temperatures during continuous use.
A 100 % ED duty cycle lets the coil remain energized continuously without overheating. Connection is made through a K4 plug conforming to DIN EN 175301-803, and the assembled unit reaches an IP65 protection level against dust and water jets. A concealed N9 manual override permits mechanical actuation when electrical control is unavailable. Flow damping is provided by a 1.0 mm throttle insert in port P identified as B10. The valve withstands 350 bar on pressure, A, and B ports, making it suitable for high-pressure circuits, while tank port pressure is limited to 160 bar to protect return lines. Maximum flow capacity is 60 l/min, ensuring adequate volume for medium-sized actuators and general machine hydraulics.
