The 4WE6W6X/EG24N9K4/V directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is installed to switch hydraulic flow paths in automated machinery. The unit is built to the ISO 4401-03-02-0-05 mounting interface so it bolts directly to size 03 subplates, and it follows the NFPA T3.5.1 R2-2002 D03 pattern for interchangeability with North American manifolds. Its nominal size of 6 defines the flow section and pairs with a maximum flow rate of 80 l/min to handle medium-capacity circuits. Work ports withstand up to 350 bar while the tank port is limited to 210 bar, allowing safe pressure separation between supply and return lines. The enclosure meets IP65 so the energized solenoids remain protected against dust and low-pressure water jets. A pair of solenoids brings the weight to 1.95 kg, and FKM seals prevent leakage when exposed to standard mineral oils.
For electrical actuation, each coil operates on 24 V DC and draws a rated current of 1.25 A, so cabinet power supplies can be sized at 30 W per coil, which matches the stated nominal power. Continuous service is supported by a 100 % duty cycle, and the winding is built to insulation class F so thermal integrity is maintained during prolonged energization. These electrical ratings enable rapid cycling of the spool in production cells that run without interruption. The permitted coil surface may reach 120 °C, which defines the upper limit for ambient and fluid conditions before derating is required. System cleanliness must not exceed ISO 4406 class 20/18/15; adhering to this contamination level prevents spool jamming and ensures reliable shifting. The valve achieves these operating limits while routing hydraulic oil between ports to control cylinders, motors, or pilot circuits without external leakage.
