The 4WE6E6X/EG24N9K4/VSO407 valve is supplied by Bosch Rexroth in the WE Directional Spool Valves series to shift hydraulic flow between actuator ports. It withstands 315 bar on pressure, A, and B ports so it can sit in main lines of medium-pressure machines, while the tank port is rated for 210 bar direct current service to protect return piping. A nominal flow of 60 l/min on the So407 configuration supports compact power unit sizing. The twin solenoid assembly draws 1.25 A from a 24 V DC source, and the allowed ±10 % voltage band keeps the armature stroke stable under supply variations. Electrical consumption is 8 W, which limits temperature rise in continuous duty. A 100 % S1 duty rating confirms that either solenoid can remain energized for extended positioning without overheating.
An IP65 K4 enclosure resists dust and water spray, permitting installation on exposed machinery frames. The coil circuit restricts switch-off overvoltage to 500 V, protecting adjacent control components, and the maximum switching rate of two cycles per second matches typical industrial sequencing speeds. FKM seals allow ambient conditions up to 50 °C and hydraulic oil temperatures up to 80 °C, so the valve handles warm factory environments without seal degradation. System cleanliness must reach ISO 4406 class 20/18/15 to prevent spool scoring and leakage. Wiring is completed through a DIN EN 175301-803 three-pole (2 + PE) connector, giving standardized plug-in access for maintenance. The assembly weighs 1.95 kg with both solenoids installed, facilitating manual replacement on manifold plates.
