The 4WE6J6X/EW100N9DJL1 directional spool valve belongs to the WE Directional Spool Valves series produced by Bosch Rexroth for hydraulic automation tasks. It directs pressurized fluid to actuators in manifolds that follow the ISO 4401-03-02-0-05 mounting pattern, allowing direct replacement in NFPA D03 subplates. A nominal size of 6 keeps passage dimensions compact while still accepting up to 60 l/min through the ac flow path, so medium-capacity circuits remain responsive. The pressure, A, and B ports withstand 350 bar, and the tank port endures 160 bar, giving designers freedom to use elevated system pressures without external reliefs. A switching frequency of two cycles per second helps cylinders change direction without undue spool wear. To avoid silting in these tight clearances, fluid cleanliness must reach ISO 4406 class 20/18/15, which dictates the filter rating for long-term reliability.
The energized solenoid on this valve operates at a rated 100 V for both 50 Hz and 60 Hz networks, with a ±10 percent voltage window to handle supply variation. Current draw equals 0.56 A at 50 Hz and 0.44 A at 60 Hz, figures that help size control transformers and protection devices. A 100 percent ED duty cycle allows the coil to remain continuously energized without cooling pauses, an advantage for machines that hold a position for extended periods. During energization the switch-on power briefly peaks at 220 VA and then settles to a 50 VA holding level, reducing overall heat generation once the spool is shifted. Even so, the coil surface can reach 120 °C, so adjacent wiring, seals, and manifold materials must tolerate this temperature during prolonged operation. These electrical characteristics combine to provide consistent actuation force under varied plant power conditions.
