4WRKE32W8-600L-3X/6EG24EK31/A5D3M

The 4WRKE32W8-600L-3X/6EG24EK31/A5D3M proportional directional valve belongs to the 4WRKE Directional Valves series manufactured by Bosch Rexroth for hydraulic automation tasks requiring high flow control. It processes a ±10 V command or feedback signal so electronic controls can position the spool with analog precision. Electrical connection is made through a DIN EN 175201-804 plug, matching common cabinet wiring layouts. The spool movement exhibits a maximum hysteresis of 1 %, helping maintain repeatable flow setpoints. An IP65 enclosure prevents dust ingress and guards against low-pressure water jets during machine wash-down. The solenoid windings draw up to 1.5 A, allowing compatibility with typical proportional amplifier outputs. At ports P, A, and B it withstands operating pressures up to 350 bar, enabling use in high-pressure circuits. With a nominal flow of 600 L/min at a 10 bar differential, it regulates large volume lines in presses or injection machines. The valve body corresponds to nominal size 32, matching ISO manifold cavities of that dimension.

The pilot stage returns oil through port Y and tolerates drain pressures up to 250 bar, so external back-pressure does not disturb spool control. Pilot supply requires 13.0 L/min, which should be provided by the system to guarantee quick positioning. Mounting follows the ISO 4401-10-08-0-94 porting pattern, facilitating interchange with other size-32 modular valves. The unit is designed for use with mineral oil of the HL or HLP classes, ensuring lubrication and corrosion protection of internal parts. Maximum response sensitivity is 0.5 %, allowing fine modulation of flow around the neutral point. Sealing elements are made from NBR to contain the pressure fluid and resist common hydraulic oils. Power to the onboard electronics is supplied at 24 V DC, matching standard machine control voltages. The complete assembly weighs 31.5 kg, a factor to consider when designing manifold support structures.
