The 4WE6E6X/EG24N9K72L directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. It shifts an internal spool to route pressure, return, and actuator lines in hydraulic automation. The solenoid operates at a nominal voltage of 24 V DC, and a voltage tolerance of ±10 % allows normal function when the supply varies. A nominal power draw of 30 W defines electrical load and heat output during service. The duty cycle is 100 % ED, so the coil can remain energized continuously without overheating. An M12 × 1 four-pole plug with an integrated suppressor diode forms the electrical connection and limits back-EMF. The mounting pattern matches ISO 4401-03-02-0-05 for direct installation on NG6 sub-plates. An IP65 rating protects the enclosure against dust and water jets, and a concealed manual override lets technicians shift the spool locally when power is absent.
Hydraulic capabilities suit medium-size actuators in production equipment. The valve passes up to 80 l/min, supporting fast cylinder movement while maintaining control accuracy. It tolerates 350 bar on ports P, A, and B, enabling use with high-pressure pumps, and the T port withstands 210 bar to handle back-pressure. A maximum switching frequency of 4.2 cycles per second defines the fastest permissible actuation rate. The coil surface may reach 120 °C, so adequate cooling airflow is required in closed cabinets. Protection class III under VDE 0580 specifies the insulation system and governs safe electrical clearances. These limits guide designers who need reliable, precise flow control in continuous-duty hydraulic machinery.
