The 4WRA10W30-2X/G24N9K4/V-589 valve is manufactured by Bosch Rexroth within the 4WRA Proportional Directional Valves series and is used to meter hydraulic flow and direct pressure-compensated actuation in automated machinery. It is built to nominal size 10 so it fits mounting patterns common to medium-flow manifolds. The spool is configured as a 4/3-way Symbol W design, allowing bidirectional cylinder control with a centered closed position. A rated flow of 30 l/min at a 10 bar pressure drop defines standard performance for steady motion. Channels p, A, and B can be loaded up to 315 bar, providing the pressure capacity required for most industrial servo loops. A 24 V DC supply energizes the proportional solenoid, while a coil resistance of 2 Ω at 20 °C sets current draw characteristics. The electronics may drive the solenoid up to 2.5 A for full stroke positioning. Mounting follows the ISO 4401-05-04-0-94 porting pattern so the valve can replace standard NG10 components without re-machining.
Peak demands are handled by a maximum flow capability of 75 l/min, ensuring reserve capacity for rapid acceleration phases. Tank port t withstands 210 bar so return pressure spikes do not compromise function. Fluid temperatures are permitted up to 80 °C, and the surrounding air may reach 70 °C, allowing installation near heat sources. The coil insulation endures 150 °C to prevent thermal damage during continuous duty cycles. A fixed connector built to DIN EN 175301-803 K4 provides the electrical interface and contributes to an IP65 ingress rating when properly installed, keeping dust and splashed oil away from the windings. FKM seals resist common hydraulic oils and elevated temperatures, extending service intervals. These characteristics align the valve with closed-loop motion platforms that need stable flow control under variable load and environment conditions.
