The 4WRZ10W6-50-7X/6EG24N9K4/M valve is produced by Bosch Rexroth within the WRZ Proportional Directional Valves series and serves to meter flow and shift direction in automated hydraulic circuits. It is built to nominal size 10 so it fits the ISO 4401-05-05-0-94 mounting pattern used in manifold blocks. The solenoid operates from a 24 V DC supply, and its coil shows 4.8 Ω resistance at 20 °C, establishing the base current demand. A 100 % duty cycle permits continuous energization without thermal rest, while the coil’s maximum temperature rating of 150 °C maintains function in hot environments. Connection is made through a DIN EN 175301-803 plug, and an IP65 enclosure rating protects against dust ingress and low-pressure water jets.
With a 10 bar differential, the valve delivers a nominal flow of 50 l/min, and it can pass up to 170 l/min when higher throughput is required. The pilot stage displaces 1.7 cm³ of oil over the full command span, and a pilot flow of 3.5 l/min enables timely spool movement. Main ports are rated for 315 bar maximum operating pressure, and the external drain at port T tolerates the same 315 bar, while port Y is limited to 30 bar to safeguard the pilot return line. The proportional solenoid accepts currents up to 1.5 A, matching typical drive amplifier outputs. These flow, pressure, and electrical limits define reliable performance in presses, molding machines, and other industrial hydraulics.
