The 4WE6G6X/EG12NDA/V/62 directional spool valve is produced by Bosch Rexroth in the WE Directional Spool Valves series to shift hydraulic flow between actuator ports in automated machinery. It operates on a nominal voltage of 12 V DC, and the coil tolerates a ±10 % voltage variation. Under that supply, the solenoid draws a rated current of 2.5 A and absorbs 30 W. Continuous service is possible because the duty cycle is 100 % in the S1 category. The armature can switch up to 4.2 times per second, and circuit protection is supported by a 500 V maximum switch-off overvoltage. Mounting follows the ISO 4401-03-02-0-05 porting pattern, and the unit may be installed in any position.
The valve functions within ambient temperatures up to 50 °C and manages hydraulic fluid temperatures up to 80 °C. It accommodates viscosities as high as 500 mm²/s, so thicker fluids remain controllable. Flow capacity reaches 80 l/min, while ports A, B, and P may be pressurized to 350 bar. The tank port withstands 210 bar, matching return-line requirements in high-pressure loops. System oil must meet ISO 4406 cleanliness class 20/18/15 to keep the spool free of contaminants, and these limits together maintain predictable switching forces throughout operation.
