The 4WE6D6X/EG12N4K4 CSA directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic oil to actuators in automation systems. Its nominal size of 6 sets the mounting interface, while the ISO 4401-03-02-0-05 porting pattern aligns the valve with standard subplates. Wet-pin, detachable solenoids simplify replacement and keep the coil isolated from the fluid. Each coil runs on 12 V DC, drawing a rated current of 2.5 A to suit mobile power supplies. A continuous duty cycle of 100% allows the solenoid to stay energized without cooling pauses, and the electromagnetic section consumes 30 W during operation. A lockable mushroom-type manual override gives operators a mechanical means to shift the spool when electrical power is absent.
The valve tolerates a maximum pressure of 350 bar on ports P, A, and B, while the tank port sustains up to 210 bar to handle elevated return pressures. It passes up to 80 l/min of hydraulic flow, and a switching frequency of 4.2 cycles per second supports fast directional changes. An IP65 enclosure guards the electrical parts against dust and water jets, and the K4 connector per DIN EN 175301-803 secures the power leads without compromising the seal. System oil must meet ISO 4406 cleanliness class 20/18/15 to avoid spool sticking and premature wear. With both solenoids installed the unit weighs 1.95 kg, keeping manifold assemblies compact.
