The 4WRA6W15-2X/G24K4/V-589 valve belongs to the 4WRA Proportional Directional Valves series produced by Bosch Rexroth for hydraulic automation tasks such as precise flow and pressure control in mobile or industrial machinery. It is energized by a 24 V DC solenoid and connects electrically through a K4 connector that provides two signal contacts and a protective earth according to Design A, streamlining wiring in control cabinets. A protection class of IP65 shields the enclosure against dust ingress and low-pressure water jets so the valve can operate on exposed manifolds. Nominal size 6 defines the spool and body dimensions, while the ISO 4401-03-02-0-05 porting pattern ensures interchangeability with standard subplates. The unit mounts on a subplate and is secured with ISO 4762 M5 × 50 (property class 10.9) screws tightened to 7 Nm, which maintains sealing integrity without distorting the body. Installation is permitted in any position, giving designers freedom to place the assembly horizontally or vertically within a manifold stack.
Hydraulic limits include a maximum operating pressure of 350 bar on pressure and service ports a, b, and p, and 210 bar on the return port t, allowing the valve to direct high-pressure flows while protecting tank lines from overloading. Under a 5-bar pressure drop per edge, it achieves a nominal flow of 15 l/min, yet it can pass up to 42 l/min when the spool is fully shifted, supporting both metering and rapid-actuation functions. Each port has an 8 mm diameter to match the flow ratings and minimize velocity losses. FKM seals resist common hydraulic oils and higher temperatures, extending service intervals in demanding circuits. The assembled component weighs 2.0 kg, so a single technician can install or replace it without lifting equipment.
