The 4WE6H6X/EG24N9K40SO43A-1852 is a directional spool valve manufactured by Bosch Rexroth in the WE Directional Spool Valves series. It directs hydraulic fluid between pump, actuator, and tank ports in automated machinery. The valve is built with a nominal size of 6 so it fits ISO size 6 subplates. Its porting pattern follows ISO 4401-03-02-0-05, allowing direct mounting to industry-standard manifolds. A maximum operating pressure of 350 bar for ports P, A, and B lets the unit handle high-force cylinders. The electromagnetic section runs on 24 V DC, draws a rated current of 1.25 A, and consumes 30 W of nominal power for consistent actuation. The coil is designed for continuous duty at 100 % ED, and the electronics accept a ±10 % voltage swing without loss of function.
Hydraulic flow up to 80 l/min can pass through the valve in direct-current operation, supplying medium-size actuators without excessive pressure drop. The tank port withstands 210 bar, supporting back-pressure circuits. An IP69K protection class shields the K40 coil against water jets and dust in mobile equipment. Electrical connection is made through a Deutsch DT04-2PA plug so cable assemblies remain sealed in the field. When manual intervention is required, a concealed N9 override allows the spool to be shifted without energizing the coil. The winding insulation supports a coil surface temperature up to 120 °C, preventing thermal damage during continuous service. Two solenoids bring the total weight to 1.95 kg, which simplifies mounting on compact valve blocks.
