The 4WE6Y22-6X/EG26N2K4KSO9 is a directional spool valve manufactured by Bosch Rexroth for the WE Directional Spool Valves series and is intended to route hydraulic flow in automated machinery. The solenoid is rated for a nominal voltage of 26 V DC, where it draws 1.17 A and therefore consumes 30 W during actuation. A 100 % duty cycle (S1) allows the coil to stay energized continuously, while a voltage tolerance of ±10 % keeps operation stable when the supply varies. Insulation class F protects the winding, and the coil surface may reach 120 °C without damage. Electrical connection is handled by a K4K plug conforming to DIN EN 175301-803, and the connector housing achieves IP65 ingress protection.
The hydraulic stage tolerates 350 bar on ports P, A, and B, whereas the tank port withstands 210 bar. Flow capacity reaches 80 l/min, and the spool may shift up to 4.2 times per second under direct current control. The mounting interface follows ISO 4401-03-02-0-05 so the valve fits standard subplates. A small mushroom-style manual override permits spool movement when power is absent, but tank pressure must be kept below 50 bar during manual actuation. These parameters define the valve’s pressure, flow, switching, and service capabilities in hydraulic automation circuits.
