The 4WRAE6W1-30-2X/G24N9K31/A1V valve is produced by Bosch Rexroth as part of the 4WRA Proportional Directional Valves series. It meters hydraulic flow under electrical control to automate motion in industrial machinery. The solenoid accepts a nominal 24 VDC supply, while the internal electronics draw up to 24 VA and limit peak current to 1.2 A. An external 4 A time-lag fuse is specified to protect the feed circuit from overloads. Mounting follows the ISO 4401-03-02-0-05 port pattern so the unit fits standard CETOP 3 subplates. The enclosure fulfills IP65 protection when the connector is correctly fitted. A concealed manual override allows spool actuation during commissioning or power loss, and the assembled valve weighs 2.5 kg.
Flow capacity reaches 42 l/min for medium-duty actuator loops, and the valve delivers a nominal 26 l/min when the differential pressure is held at 5 bar. Maximum working pressure is 350 bar on pressure and service ports A, B, and P, with the tank port rated to 210 bar. Hydraulic oil temperatures may be as high as 70 °C without performance loss. FKM sealing elements maintain leakage control under heat and chemical exposure. These limits support consistent proportional control across a wide range of hydraulic automation tasks.
