The 4WE6X6-6X/EG12N9K4 directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth to route hydraulic flow in automated systems. It is built in valve size 6, a format that matches the ISO 4401-03-02-0-05 subplate interface for compact manifold mounting. A DIN EN 175301-803 (K4) electrical connector supplies a 12 V DC coil, and the winding draws a rated current of 2.5 A while consuming 30 W of nominal power to shift the spool. Insulation class F allows the coil to tolerate elevated operating temperatures, and a maximum switch-off overvoltage of 500 V protects the electronics during de-energization. Continuous service is supported by a 100 % ED duty cycle, while an IP65 protection class guards the housing against dust and water spray in factory environments.
The hydraulic section is rated for a maximum pressure of 350 bar on ports P, A, and B, with the tank port permitted up to 210 bar to suit high-pressure circuits. During operation it can pass up to 80 l/min, ensuring adequate flow for medium-sized actuators. A cleanliness class of ISO 4406 20/18/15 is required to prevent spool sticking and maintain service life. The valve can be installed in any position, giving designers flexibility when arranging stacked manifolds. A concealed manual override identified by code N9 lets maintenance staff shift the spool without power while avoiding accidental activation. These features complete the hydraulic and mechanical profile needed for reliable directional control in automation lines.
