The 4WE6Y22-6X/EG26N9K4KSO9 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series for controlling actuator flow in hydraulic automation systems. It withstands a maximum operating pressure of 350 bar so it can manage high-pressure circuits, and it passes up to 80 l/min to handle medium flow rates in mobile or industrial equipment. The porting pattern ISO 4401-03-02-0-05 aligns the body with standardized sub-plates, while a clamping length of 42 mm sets the required manifold pocket depth. Correct installation calls for mounting screws tightened to 7 Nm to maintain seal compression. An IP65 ingress rating shields the coil and core tube from dust and water jets, and a 100 % ED duty cycle keeps the solenoid energized without overheating during continuous service. Voltage tolerance of ±10 % lets the coil accept modest supply variations without a loss of function.
The solenoid is wound for 26 V DC, drawing a rated current of 1.17 A and dissipating 30 W, allowing control circuits with low-voltage power supplies to operate the valve reliably. Electrical connection is made through a K4K plug conforming to DIN EN 175301-803, which simplifies wiring changes in field service. A concealed N9 manual override gives technicians a way to shift the spool mechanically, and the override can be used when the tank line pressure is up to 50 bar. The tank port itself may reach 210 bar during dynamic operation without exceeding design limits. Fluid cleanliness must not exceed ISO 4406 20/18/15 to prevent spool sticking and seat wear.
