The 4WRAB6W03-1X/G12N9K4/MR belongs to the 4WRA Proportional Directional Valves series and is produced by Bosch Rexroth for hydraulic automation where electrical inputs modulate spool position and flow direction. It follows the ISO 4401-03-02-0-05 mounting pattern to align with standardized manifolds, and uses subplate mounting so the body sits directly on the base block without additional piping. The nominal size is 6, matching compact systems that still require precise metering. Four ports are provided to connect pressure, tank, and actuator lines. Three switching positions allow centered neutral and two working states for bidirectional cylinder control. The spool is identified by symbol W, defining the internal flow paths for each position. A covered manual override labeled N9 permits local shifting when power is unavailable. The coil operates from a 12 V DC supply, allowing integration into low-voltage mobile or industrial controls.
The coil resistance is 4.8 Ω at 20 °C, establishing the electrical load seen by the driver. Maximum coil power is limited to 30 W so thermal rise stays within design limits during continuous duty. Wiring is completed through an EN 175301-803 three-pole (2 + PE) connector that provides secure contact and protective grounding. The housing carries an IP65 rating, protecting internal parts against dust ingress and water jets. Operating ports a, b, and p withstand pressures up to 350 bar, while the tank port t is rated for 210 bar. The valve handles flow rates to 30 L/min without exceeding pressure drop limits. NBR seals marked MR are fitted to maintain compatibility with common mineral-based hydraulic fluids.
