Rexroth 4WE 6 E6X/EG24N9K4 – NG6 4/3 Hydraulic Solenoid Directional Valve, E Spool, 24VDC

✅ Rexroth 4WE 6 E6X/EG24N9K4 is a hydraulic solenoid-operated directional valve from the WE 6 Series, designed to control hydraulic oil flow direction in industrial hydraulic systems. The valve features a 4/3 configuration, three switching positions and two solenoids for precise hydraulic actuator control.

✅ The model has a nominal size of NG6 / Size 6 and uses the ISO 4401 and CETOP-RP 121 H mounting standard. This makes it suitable for standard hydraulic manifolds and sub-plates while maintaining a compact installation footprint.

✅ The E spool provides a closed-center configuration in which P, T, A and B are blocked in the center position. This design is suitable for hydraulic circuits where the actuator needs to remain in its controlled state while the directional valve is in neutral.

✅ The valve uses two 24VDC solenoids to shift the spool in either direction. When the control signal is removed, the spring returns the spool to the center position, making the valve suitable for PLC-controlled automation and industrial hydraulic machinery.

✅ The EG24N9K4 configuration identifies a high-performance wet-pin solenoid with 24VDC supply, together with a concealed auxiliary actuation mechanism N9. The K4 connection is a component plug according to DIN EN 175301-803.

✅ The Rexroth 4WE 6 E6X/EG24N9K4 provides a maximum operating pressure of 350 bar and a maximum flow of approximately 80 L/min, making it suitable for relatively high-pressure industrial hydraulic applications.

✅ Its robust construction and standardized mounting interface make this valve suitable for hydraulic presses, stamping machines, machining equipment, lifting systems and automated hydraulic machinery.

✅ The 24VDC solenoid configuration provides convenient integration with PLCs, relays and common industrial control systems.

Quick Selection and Usage Guide

✅ Select the E spool configuration when the application requires a closed-center neutral condition.

✅ Confirm the 24VDC control voltage before wiring the solenoid coils.

✅ Ensure that the mounting surface complies with the ISO 4401/CETOP 03 interface.

✅ Select hydraulic oil compatible with NBR seals and the actual operating conditions.

✅ Install the valve in the correct orientation, tighten mounting screws properly and check for leakage before commissioning.

✅ During operation, periodically inspect the solenoid coils, electrical connectors, hydraulic oil cleanliness and spool movement to maintain reliable system performance.
