The 4WRA6E15-2X/G24K4/V belongs to the 4WRA Proportional Directional Valves series from Bosch Rexroth and provides controlled flow direction in hydraulic automation circuits. Valve size 6 (NG6) fixes the mounting envelope for compact manifold layouts, while its subplate mounting style allows fast replacement without disturbing pipework. The ISO 4401-03-02-0-05 porting pattern standardizes interface dimensions so the valve can be swapped with similar units. A maximum system pressure of 350 bar lets the valve handle high-force actuators, and the nominal flow of 15 l/min at a 5 bar pressure drop per edge supports accurate metering. The 24 V DC supply voltage connects directly to common machine control power rails, and the K4 control electronics interface matches Bosch Rexroth amplifier modules for proportional command signals. Because no manual override is fitted, unintended spool shifts during automated operation are avoided.
The valve accepts up to 42 l/min, giving additional flow capacity for rapid cylinder movement when required. Return port pressure may reach 210 bar, protecting tank lines in regenerative circuits. An IP65 protection class shields the enclosure from dust and water jets encountered on factory floors. Fluid cleanliness must stay within ISO 4406 class 20/18/15 to prevent spool wear and sticking. FKM seal material resists aggressive hydraulic oils and supports elevated service temperatures, and the surface temperature limit of 150 °C prevents thermal degradation of elastomers and coil insulation. Spool symbol E identifies the metering geometry used for proportional directional control, and a weight of 2.0 kg permits easy manual installation inside machinery.
