The 4WRA6W07-2X/G24N9K4/V valve belongs to the 4WRA Proportional Directional Valves series from Bosch Rexroth and is used to meter flow and shift direction in automated hydraulic circuits. It is built in valve size 6 and withstands system pressures up to 350 bar on ports a, b, and p. A 24 VDC solenoid coil provides the proportional command signal, allowing the unit to deliver a nominal flow of 7 l/min at a 5 bar pressure drop per edge and a maximum flow of 42 l/min when fully energized. The interface follows the ISO 4401-03-02-0-05 porting pattern, and the body mounts on a subplate with M5 × 50 ISO 4762 screws that are tightened to 7 Nm. These mounting details enable quick replacement and accurate alignment in manifolds and standard base plates.
An IP65 protection class shields the electrical assembly from dust and low-pressure jets of water in industrial environments where the ambient temperature can reach +80 °C. Hydraulic fluid may be admitted up to +70 °C, provided cleanliness is maintained at 20/18/15 per ISO 4406 to protect the metering spool and seat. A concealed manual override lets technicians shift the spool during commissioning or power loss without disturbing the electrical connection. FKM seals are fitted to resist common mineral oils and many synthetic fluids, while the complete assembly weighs 2.0 kg for manageable handling during service or replacement.
