The 4WE6D6X/EG24N9DK24L2/ZV/62SO43A1791 directional spool valve is built by Bosch Rexroth within the WE Directional Spool Valves series. It shifts hydraulic flow between actuator ports for automation circuits. The valve is supplied in nominal size 6, which matches NG6 subplate layouts for compact manifolds. Its porting pattern follows ISO 4401-03-02-0-05 so it bolts directly to standard subplates without adapter blocks. The D-type spool geometry establishes the flow paths required for double-acting cylinders. A maximum flow capacity of 80 l/min allows medium-rate motion while maintaining system efficiency. The valve withstands 350 bar on pressure, A, and B ports, making it suitable for high-pressure machines. A 24 V DC coil powers the solenoid, and the ±10 % voltage tolerance keeps performance stable when supply fluctuates. Electrical consumption is limited to 30 W, which helps reduce cabinet heat and power demand.
An M12x1 four-pole DK24L connector provides quick plug-in wiring and simplifies maintenance. The housing carries an IP65 rating, so dust ingress and low-pressure water jets do not compromise the coil or core tube. A concealed manual override labeled N9 lets technicians shift the spool mechanically during commissioning or power loss. Continuous-duty capability is indicated by a 100 % S1 duty cycle, allowing the solenoid to remain energized without thermal derating. FKM seals are fitted to handle common hydraulic oils and elevated temperatures. The 22 mm clamping length defines the space required under the retaining bolts and ensures proper compression on the subplate gasket. System oil must meet ISO 4406 cleanliness class 20/18/15 to prevent spool sticking and premature wear. Tank and drain ports may be pressurized up to 210 bar, enabling return-line circuits that operate above atmospheric pressure.
