The 4WE6E6X/EG12N2K4K directional spool valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth for electrically controlled hydraulic circuits. It runs on a 12 V DC coil that draws 2.5 A, allowing direct connection to low-voltage power sources. The coil requires 30 W of nominal power, keeping electrical load modest on auxiliary supplies, and it remains reliable within a ±10 % voltage window. Continuous energization is possible because the duty cycle is 100 % ED. Electrical termination is handled by a 3-pole (2+PE) connector in accordance with DIN EN 175301-803, which speeds installation. A small mushroom-style manual override permits mechanical actuation when the solenoid is not powered. The winding resists switch-off transients up to 500 V, protecting insulation during de-energization, and the complete valve with two solenoids weighs 1.95 kg, making manual handling straightforward.
The hydraulic section passes up to 80 l/min, so medium-capacity actuators can be driven without excess pressure drop. Ports P, A, and B accept operating pressures as high as 350 bar, while port T is rated for 210 bar to safeguard return lines. A maximum switching frequency of 4.2 cycles per second supports applications that demand rapid directional changes. The porting pattern follows ISO 4401-03-02-0-05, and the mounting interface matches NFPA T3.5.1 D03, ensuring compatibility with standard subplates. Environmental sealing meets IP65, preventing dust ingress and water jets from affecting the coil or connector in harsh service areas. These combined characteristics define the valve’s performance envelope within hydraulic automation systems.
