The 4WRA6E30-2X/G24K4/V is manufactured by Bosch Rexroth for the 4WRA Proportional Directional Valves series. The unit meters hydraulic flow in closed-loop control systems, allowing automated actuators to change speed and direction with an electrical command signal. With a size 6 body, it installs on a subplate connection that conforms to porting pattern ISO 4401-03-02-0-05. Supply power for the proportional solenoid is 24 V DC, and the coil is terminated through a 2-pole plus protective-earth connector coded K4. The enclosure carries an IP65 rating so it resists dust ingress and low-pressure water jets when the mating plug is fitted. FKM elastomer seals are used to handle common industrial fluids, and internal passages remain reliable when oil cleanliness is maintained at ISO 4406 class 20/18/15. Despite its functional capability, the valve weighs only 2.0 kg, which eases manifold assembly and service handling.
The hydraulic performance envelope supports 350 bar on ports A, B, and P, while the return port T is limited to 210 bar, enabling safe circuit design across pressure zones. Nominal flow reaches 26 l/min per control edge at a 5-bar pressure drop, and the spool can pass up to 42 l/min when fully actuated to satisfy higher momentary demands. Surface temperature may rise to 150 °C, so surrounding components must tolerate that thermal level. Bosch Rexroth specifies ISO 4762 M5 × 50 class 10.9 mounting screws, each tightened to 7 Nm, to secure the housing to the subplate without distortion. This hardware and torque setting keep the valve aligned with the manifold sealing land and sustain the rated pressures over long duty cycles. These mechanical and thermal limits complement the electrical and sealing features described earlier to complete the product’s technical profile.
