The 4WRA6V30-2X/G24N9K4/V-589 valve belongs to the 4WRA Proportional Directional Valves series produced by Bosch Rexroth for precise hydraulic automation. It attaches to a manifold through subplate mounting, and the interface follows porting pattern ISO 4401-03-02-0-05 to match common CETOP size 03 blocks. Continuous service pressure reaches 350 bar at ports A, B, and P, while port T is limited to 210 bar to protect the return line. A maximum flow of 42 l/min accommodates medium-duty actuator speeds, and nominal flow of 26 l/min at a 5 bar differential per metering edge provides a repeatable reference point for circuit design. The enclosure meets IP65, preventing dust ingress and water spray during cabinet mounting. Overall weight is 2.0 kg, allowing installation without heavy support hardware.
Hydraulic fluid may enter the valve between –20 °C and +70 °C, permitting cold-start operation and sustained duty at elevated temperatures. Recommended viscosity lies between 30 and 46 mm²/s, yet the unit remains operable across a wider range of 20 to 380 mm²/s when necessary. System cleanliness must be held to ISO 4406 class 20/18/15 so the spool slides without contamination-induced wear. Hysteresis is kept below 5 %, limiting output deviation when command direction reverses. The range of inversion remains under 1 %, so overlap deadband is minimal during flow reversal. Response sensitivity better than 0.5 % enables small signal changes to adjust spool position quickly, supporting accurate proportional control in closed-loop hydraulic circuits.
