The 4WE6X7-6X/EG12N9K4 valve is produced by Bosch Rexroth as part of the WE Directional Spool Valves series and directs hydraulic flow in automated systems. At size 6, it fits circuits that use the ISO 4401-03-02-0-05 D03 mounting pattern, allowing quick interchange with standard subplates. The coil is designed for a nominal voltage of 12 V DC and draws a rated current of 2.5 A, so control cabinets can use low-voltage supplies. Nominal power is limited to 30 W to keep heat generation within expected cabinet limits, and the coil can be energized continuously thanks to a 100 % duty cycle rating. Environmental sealing reaches IP65, maintaining operation when dust or water jets are present. A concealed manual override coded N9 permits local actuation without exposing internal parts.
The electrical connector follows DIN EN 175301-803 form K4, simplifying wiring with standard plugs and letting maintenance crews swap coils without specialized tools. Maximum flow in direct current operation is 80 l/min, supporting medium throughput circuits. The valve withstands 350 bar at ports P, A, and B, while the tank port handles up to 210 bar, so it can be applied on high-pressure lines without external pressure reducers. Switching speed is suited to cyclical tasks, with a maximum frequency of 4.2 cycles per second, and surface temperature of the coil is limited to 120 °C to protect adjacent components. The unit weighs 1.95 kg, which eases installation on compact manifolds.
