4WRKE27W6-500L-3X/6EG24K31/A5D3M

The 4WRKE27W6-500L-3X/6EG24K31/A5D3M valve belongs to the 4WRKE Directional Valves series from Bosch Rexroth and regulates hydraulic actuator speed and direction in automated machinery. Integrated control electronics remove the need for a separate amplifier, so cabinet wiring is simplified. A supply voltage of 24 V DC powers the circuits, while a maximum supply current of 1.5 A maintains stable operation under continuous load. During rapid spool shifts the unit can accept an impulse load up to 3 A, preventing nuisance trips when command signals change abruptly. The proportional solenoid with a removable coil converts input current to smooth spool movement for accurate flow metering. Electrical connection is made through a DIN EN 175201-804 connector, providing a standardized interface for field wiring. External pilot oil supply ensures the control stage is fed with clean, pressure-stabilized oil, and an external pilot oil drain prevents back-pressure from disturbing the spool position. Channels P, A, and B withstand operating pressures to 210 bar, allowing the valve to handle mid-pressure circuits in presses, molding machines, and similar equipment.

The hydraulic base adopts the ISO 4401-08-07-0-94 porting pattern so it fits manifolds already common in large industrial systems. Nominal flow is rated at 500 L/min for routine motion tasks, and the body can pass up to 1000 L/min when peak actuator speed is required. Six mounting screws sized M12 × 60, grade 10.9, clamp the housing to the manifold to resist vibration and shock. An IP65 protection class shields the internal electronics from dust ingress and low-pressure water jets, supporting installation on open factory floors. NBR sealing elements block leakage of mineral-based hydraulic fluids and tolerate typical petroleum additives. Total weight is 17 kg, enabling handling by a single technician while still providing the mass needed to damp pressure pulsations. Together, these characteristics let the valve deliver precise, high-flow control in demanding automated hydraulic systems.
