The 4WE6D6X/EG12N4K4 valve is manufactured by Bosch Rexroth and belongs to the WE Directional Spool Valves series, where it shifts hydraulic flow to automate cylinders or motors. A 12 V DC solenoid rated for 2.5 A produces 30 W to move the spool, and the supply may vary by ±10 % without affecting function. Continuous service is permitted because the coil is specified for a 100 % duty cycle, while insulation class F permits elevated winding temperatures during prolonged energization. The DIN EN 175301-803 three-pin connector simplifies wiring and maintains correct polarity. An IP65 housing prevents dust ingress and low-pressure water intrusion, securing the valve in mobile or factory wash-down zones. When power is removed, a built-in suppressor limits switch-off overvoltage to 500 V, protecting driver electronics.
The hydraulic section handles up to 350 bar on ports p, A, and B, and it allows 80 l/min flow to pass with minimal pressure loss, making the valve suitable for medium-sized actuators. Tank port T withstands 210 bar, so back-pressure devices can be fitted without risk. A lockable mushroom-style manual override lets maintenance staff shift the spool mechanically; the override endures 50 bar tank pressure during use. Mounting follows the ISO 4401-03-02-0-05 pattern and matches the NFPA D03 interface, enabling interchange with common subplates. These mechanical details, combined with a small electrical package, let the valve integrate cleanly into compact hydraulic manifolds.
