The 4WRAB6G00-11/G12N9K4/M SO43A-1467 valve belongs to the 4WRA Proportional Directional Valves series from Bosch Rexroth and is intended for precise hydraulic automation tasks. It is a direct operated unit in nominal size 6, allowing installation on NG6 manifolds. Subplate mounting is provided through the ISO 4401-03-02-0-05 interface that matches NFPA D03 patterns. The body offers four main ports and three switching positions to manage circuit flow under proportional control. Electrical actuation is supplied by an external amplifier driving the coil at 12 V DC, and connections are made with an EN 175301-803 three-pin plug that includes a protective earth conductor.
The valve delivers a nominal flow of 12 l/min and can pass up to 30 l/min at full command, supporting dynamic actuator speeds while sustaining a maximum operating pressure of 350 bar. Compatible hydraulic media include HL, HLP, HLPD, HVLP, HVLPD, and HFC fluids, so it suits mineral-oil and fire-resistant systems. NBR seals retain these fluids and resist wear in continuous service. The assembled unit weighs 2.00 kg for straightforward handling during installation or replacement, and its proportional spool design reflects Bosch Rexroth’s long experience in stable, high-response electrohydraulic control.
