The 4WE6J6X/EG24NK4/N12 directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for hydraulic automation tasks that require precise switching of flow paths. It operates on a nominal voltage of 24 V DC and draws a rated current of 1.25 A, yielding 30 W nominal power for consistent solenoid force. A voltage tolerance of ±10 % maintains performance despite supply fluctuations, while a duty cycle of 100 % permits continuous energization without thermal derating. The coil surface may reach 120 °C during sustained operation, so appropriate thermal clearance must be provided. Electrical connection is made through a K4 connector compliant with DIN EN 175301-803, and the ISO 4401-03-02-0-05 mounting pattern fits standard CETOP 03 subplates. With two solenoids installed the valve weighs 1.95 kg, allowing straightforward handling during assembly.
The unit includes a manual override, enabling the spool to be shifted mechanically when power is absent; this function can be applied safely up to 50 bar on the tank line. Hydraulic ratings cover a maximum operating pressure of 350 bar on ports P, A, and B, while the tank port withstands 210 bar during DC operation. The design supports a maximum flow of 80 l/min, allowing stable performance in medium-capacity circuits. A 1.2 mm throttle insert located in ports A and B moderates inrush flow and helps control actuator speed. These combined parameters preserve spool stability under full rated flow, give operators a fallback option through the override, and keep the assembly within its defined pressure envelope.
