The 4WRKE10W6-100L-3X/6EG24EK31A1D3V directional valve belongs to the 4WRKE Directional Valves series and is produced by Bosch Rexroth. It translates analog voltage commands into controlled spool movement to route oil in hydraulic automation. Nominal size 10 fits mid-range circuit manifolds, while the linear spool characteristic keeps the gain constant across the stroke for predictable actuator speed. A nominal flow of 100 L/min at a 10 bar differential meets common servo cylinder demands, and the valve tolerates system pressures up to 315 bar for high-pressure machinery. Internal pilot oil supply draws control oil directly from the pressure port, and external pilot oil drain returns pilot oil to tank to avoid backpressure. The integrated electronics accept a ±10 V command signal for proportional positioning and require a 24 VDC power feed to energize the amplifier stage.
Peak flow capability reaches 170 L/min, giving headroom for transient surges without spool saturation. Response sensitivity of 0.5 % or better enables small command changes to register at the actuator, and hysteresis held within 1 % minimizes deadband during bidirectional cycling. The coil draws a maximum supply current of 1.5 A, so panel fusing can be sized accordingly. An IP65 ingress protection rating keeps dust and low-pressure water jets from entering the housing, and the plug pattern DIN EN 175201-804 streamlines field wiring with standardized connectors. FKM seals withstand mineral oil and elevated temperature, ensuring long service life. The assembled unit weighs 8.7 kg, allowing installation by one technician without lifting equipment.
