The 4WE6H6X/EG12N4K4 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs pressurized fluid to cylinders or motors in hydraulic automation. It runs on a 12 V DC supply, drawing 30 W so coil temperature stays within limits, and accepts a ±10 % voltage swing to cope with unstable power sources. The coil is designed for a 100 % ED duty cycle, allowing continuous energization during long holding periods. Wiring is done through a DIN EN 175301-803 three-pole plug for quick interchange, while an IP65 enclosure protects the solenoid against dust and water jets in mobile machinery.
The valve handles 80 l/min while maintaining 350 bar on ports P, A, and B, and the tank port tolerates 210 bar during direct-current service. A small lockable mushroom button gives a manual override, but tank pressure must stay below 50 bar when it is used. With a switching rate of 4.2 cycles per second, the unit responds fast enough for typical on-off control loops. It requires HLP mineral oil that meets DIN 51524 and demands fluid cleanliness of ISO 4406 class 20/18/15 to limit wear on the spool and body. These limits support reliable direction changes in high-pressure hydraulic circuits.
