The 4WRA10E60-2X/G24N9K4/V-589 proportional directional valve belongs to the 4WRA Proportional Directional Valves series and is produced by Bosch Rexroth for closed-loop hydraulic automation. Designed to meter oil flow and shift actuator direction, the unit is supplied in nominal size 10 to match medium-frame manifolds. It attaches by subplate mounting, and its interface follows porting pattern ISO 4401-05-04-0-94 for interchange with standard bases. The internal spool is identified by symbol E, determining the controlled flow paths during actuation. Ports A, B, and P can be pressurized up to 315 bar, while the return port T is limited to 210 bar. Under a 10-bar differential the valve delivers a rated flow of 60 l/min, and it can pass up to 75 l/min when fully shifted. The solenoid is energized with a 24 V DC supply, allowing integration with common machine controllers.
Electrical performance is defined by a coil resistance of 2 Ω at 20 °C, which limits inrush and supports a maximum solenoid current of 2.5 A. Continuous energization is permitted because the duty cycle is 100 %, and the winding insulation tolerates temperatures up to 150 °C. Connection is made through a DIN EN 175301-803 plug, providing quick field replacement. The hydraulic circuit must maintain oil cleanliness at ISO 4406 (c) 20/18/15 or better to avoid spool wear. Fluid sealing is handled by FKM elastomers, extending compatibility with higher-temperature or synthetic fluids. Together these characteristics qualify the valve for precise and durable flow control in industrial hydraulic systems.
