The 4WRA6E15-2X/G24N9K4/V-589 valve is manufactured by Bosch Rexroth within the 4WRA Proportional Directional Valves series and is used to meter and redirect flow in automated hydraulic circuits. A 24 V DC solenoid supplies the energy needed to shift the spool, providing proportional response to electrical control signals. The unit delivers a nominal flow of 15 l/min and can accommodate up to 42 l/min when greater actuator velocity is required. Ports P, A, and B withstand pressures to 350 bar, while the T port is rated for 210 bar to protect the return line. Subplate mounting simplifies replacement during maintenance, and the ISO 4401-03-02-0-05 porting pattern aligns with standard manifolds. Each pressure port has an 8 mm diameter that balances flow capacity with compact size. A concealed manual override permits manual spool shift during commissioning or power loss without protruding levers.
M5 × 50 class 10.9 screws secure the valve to its manifold, and a tightening torque of 7 Nm maintains gasket compression without overstressing the threads. An IP65 protection class guards the enclosure against dust and low-pressure water jets encountered in industrial environments. FKM sealing elements resist mineral oils and elevated temperatures, while a surface temperature limit of 150 °C prevents thermal damage to internal components. Hydraulic fluid must meet ISO 4406 20/18/15 cleanliness to avoid spool sticking or premature wear. The valve’s weight of 2.0 kg allows one-person installation and minimizes load on lightweight mounting plates.
