4WE6D73-6X/EG24N9DK24L2/A12V

The 4WE6D73-6X/EG24N9DK24L2/A12V directional spool valve is built by Bosch Rexroth for the WE Directional Spool Valves series. It shifts hydraulic flow between actuator ports and pumps in automated circuits. The valve operates on a nominal voltage of 24 V DC, which matches standard machine power supplies. A rated current of 1.25 A drives the solenoid coil, and the electrical section absorbs 30 W of nominal power, allowing consistent magnetic force. The duty cycle is 100% ED so the coil can remain energized continuously without thermal overload. Voltage tolerance of ±10% protects performance when supply lines fluctuate, while a maximum switch-off overvoltage of 500 V prevents insulation damage during coil de-energization. The enclosure meets IP65 under EN 60529, and the design is assigned protection class III according to VDE 0580, ensuring safe operation in control cabinets. FKM seals are fitted to resist common hydraulic fluids and elevated temperatures.

The hydraulic section supports a maximum flow of 80 l/min, enabling medium-capacity circuits to move oil without excessive pressure loss. Maximum operating pressure at ports A, B, and P is limited to 350 bar, whereas the tank port can withstand up to 210 bar, giving designers clear boundaries for return-line sizing. The valve follows porting pattern ISO 4401-03-02-0-05, simplifying manifold mounting with industry-standard footprints. A switching frequency of up to 4.2 cycles per second enables rapid actuation in positioning or clamping tasks. Cleanliness class ISO 4406 20/18/15 indicates required fluid filtration to maintain spool accuracy. Solenoids and housing together weigh 1.95 kg, which facilitates manual installation and service. This combination of flow capacity and pressure boundaries aligns with medium-frame pumps and cylinders used in material handling machines. These characteristics let the spool valve direct pressure reliably in automated hydraulic equipment.
