4WE6G6X/EG24N9DK25L

The 4WE6G6X/EG24N9DK25L valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. As a solenoid-actuated spool unit, it directs hydraulic flow in industrial automation circuits. It is built in size 6, which defines the interface dimensions and flow capacity of the body. The valve mounts on subplates drilled to the ISO 4401-03-02-0-05 pattern, also known as NFPA D03, so it fits standard manifolds. Channels a, b, and p can be pressurized up to 350 bar, allowing the component to manage high-pressure lines without fatigue. Under direct-current excitation it passes up to 80 l/min, providing adequate volume for medium-power actuators. Continuous service is supported by a 100 % ED duty cycle, meaning the coil may remain energized without enforced cooling intervals. The solenoid is rated for 24 V DC, matching common machine control supplies. At that voltage the coil draws 1.25 A, defining the driver output needed from the electrical cabinet.

Connection to the solenoid is made through a DK25L five-pole Mini-Change plug, enabling quick replacement during maintenance and reducing wiring errors. A concealed manual override identified by code N9 lets technicians shift the spool locally while protecting the button from accidental activation. When this override is used, tank pressure must not exceed 50 bar to avoid damage to the push pin. The return port t can handle 210 bar in DC operation, so the valve tolerates elevated back-pressure when cylinders regenerate flow. Sealing elements are manufactured from NBR, making the valve compatible with mineral oils and many common hydraulic fluids. System cleanliness should be maintained at ISO 4406 class 20/18/15 or better to prevent spool sticking and premature wear in the directional stage. Electrical energy consumption is 30 W, which simplifies thermal calculations for enclosures. During operation the external coil surface may reach 120 °C, so wiring and nearby materials must tolerate elevated temperatures.
