The 4WRA6W30-2X/G24N9K4/V-589 proportional directional valve belongs to the 4WRA Proportional Directional Valves series from Bosch Rexroth and meters hydraulic flow in automation circuits where precise position or speed control is required. The solenoid operates from a 24 V DC supply voltage so the valve can be driven directly by common machine controllers. Its K4 electrical interface enables external control signals to modulate the spool position without integrated electronics. A W spool symbol identifies metering geometry that yields balanced flow for both service ports. Nominal flow capability reaches 42 l/min, providing adequate capacity for medium-size actuators. Contamination limits are defined by cleanliness class ISO 4406 (c) 20/18/15 to protect the fine spool lands. The valve attaches by subplate mounting, and the ISO 4401-03-02-0-05 porting pattern establishes interchangeability within standardized manifolds.
Ports a, b, and p withstand operating pressures up to 350 bar, while the t port is rated for 210 bar to secure the return line. An 8 mm port diameter on all four connections maintains consistent pressure drop across the usable flow range. Hydraulic fluid may reach a maximum temperature of 70 °C without affecting performance. Electrical parts carry an IP65 protection class, sealing them against dust and water jets in typical factory environments. A concealed manual override designated N9 lets maintenance personnel shift the spool when power is absent. FKM seals contain the working fluid under the stated pressure and temperature limits. Installation uses M5 × 50 – 10.9 mounting screws tightened to 7 Nm to hold the body securely against the subplate, and the class 10.9 rating of the screws resists vibration, maintaining connection integrity in mobile or cyclic machinery.
