The 4WRA6E1-15-2X/G24N9K4/V-589 proportional directional valve belongs to the 4WRA Proportional Directional Valves series from Bosch Rexroth and is used to meter hydraulic flow in automated motion circuits. It is powered from a 24 V DC supply, and the K4 external electrical interface allows the coil to be connected through a standard plug without opening the enclosure. The valve attaches to a manifold by subplate mounting, matching the ISO 4401-03-02-0-05 porting pattern so line connections remain consistent across systems. Individual ports have an 8 mm bore, and nominal flow reaches 15 l/min at a pressure drop of 5 bar per edge while peak flow capacity is 42 l/min when passages are fully open. Installation can be in any orientation to simplify layout, and a concealed manual override lets technicians shift the spool during commissioning or power loss without affecting the normal sealing surfaces.
The housing carries an IP65 protection class, so dust ingress and water jets will not disrupt operation in typical machine halls. Surface temperature is limited to 150 °C which prevents damage to adjacent hoses or wiring when the coil is energized for long periods. All dynamic seals are made from FKM to maintain chemical compatibility with common hydraulic oils at elevated temperatures. The valve is fastened with two M5 x 50 screws that follow ISO 4762, and tightening torque is specified at 7 Nm to secure the body against the subplate without distorting the sealing face. A mean time to dangerous failure of 150 years indicates long service intervals in safety-related installations, and the assembled unit weighs 2.0 kg which eases manual handling during replacement or line retrofits.
