The 4WE6E6X/EW230N9DAL/B12V valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and directs hydraulic flow in automation circuits by shifting a spool with an AC-powered solenoid. The unit is built in size 6 for compact installations, and it mounts on subplates that follow NFPA T3.5.1 R2-2002 D03 while matching the ISO 4401-03-02-0-05 port layout. A 230 V AC 50/60 Hz coil draws 220 VA at switch-on to move the spool, after which holding power falls to 50 VA to limit thermal load. Continuous currents are 0.16 A at 50 Hz and 0.17 A at 60 Hz, helping designers size fuses and contactors accurately. Wiring enters through a DAL 1/2-14 NPT conduit fitting that seals the electrical connection against oil and moisture.
The valve tolerates a 100 % ED duty cycle so the coil may remain energized indefinitely during long machine cycles. A concealed manual override identified as N9 lets technicians change spool position without power. Hydraulic limits include a maximum operating pressure of 350 bar on pressure and work ports and 160 bar on the tank port, enabling use in high-pressure circuits that generate significant back pressure. Flow capacity reaches 60 l/min, and a 1.2 mm throttle insert in port B, coded B12, can restrict that line to fine-tune actuator speed. FKM sealing resists aggressive fluids and elevated temperatures, supporting reliable operation over extended service intervals.
