4WE6X7-6X/EG24N9K4/62SO43A-1042

The 4WE6X7-6X/EG24N9K4/62SO43A-1042 is manufactured by Bosch Rexroth for the WE Directional Spool Valves series and is intended to route pressure fluid between actuator ports in hydraulic automation. A nominal voltage of 24 VDC permits the solenoid coils to be powered from standard machine control supplies, and the ±10 % voltage tolerance keeps the valve operational despite supply fluctuations. The coil draws a rated current of 1.25 A and consumes 30 W, providing the magnetic force needed to shift the spool under load. Continuous duty is supported by a 100 % ED rating, so the coil can remain energized without enforced cooling periods. Switching operations can occur up to 4.2 cycles per second, giving the valve adequate responsiveness for medium-speed control loops. Electrical connection is made through a K4 plug conforming to DIN EN 175301-803, which streamlines wiring with molded connectors. An IP65 protection class resists dust ingress and water jets when the connector is properly installed, while a concealed N9 manual override lets maintenance staff shift the spool during commissioning or power loss without exposing the mechanism.

The design withstands a coil surface temperature of 120 °C during direct-current operation, allowing reliable service when the envelope is mounted in warm manifolds. Hydraulic limits include a maximum operating pressure of 350 bar at ports A, B, and P and a 210 bar limit at the tank port T, ensuring compatibility with high-pressure supply lines yet protecting return components. Flow capability reaches 80 l/min, so the valve can handle medium frame pumps without excessive pressure drop. The porting pattern follows ISO 4401-03-02-0-05, enabling direct mounting on subplates that share this common footprint. A locating hole secured by an ISO 8752 3 × 8 locking pin keeps the housing aligned during installation and prevents rotation from line vibration. With two solenoids fitted, the assembly weighs 1.95 kg, which simplifies handling during manifold service.
