Rexroth 4WE6M6X/EG24N9K4 Solenoid Directional Valve

Overview

The Rexroth 4WE6M6X/EG24N9K4 identifies an NG6, component-series 6X directional valve with spool symbol M. This catalog configuration uses two solenoids with spring centering. Provide the full nameplate and circuit requirements so the supplied unit can be confirmed.

Checking a pressure-connected center

The M spool interconnects P, A and B at center while blocking T. Both actuator lines therefore communicate with the pressure supply. For a cylinder with unequal piston areas, this condition can create a net force. Confirm the circuit design and expected actuator movement; do not specify the M center as a neutral load-holding state.

Key configuration details

• Four main ports and 3 switching positions; spool symbol M.
• 2 solenoids; spring-centered.
• G24: 24 V DC actuation.
• K4: individual 3-pole connector interface, 2 + PE; mating connector ordered separately.
• Subplate mounting to ISO 4401-03-02-0-05.
• NBR seals for the specified catalog configuration.

Configuration code

4WE6 denotes a four-port solenoid-operated directional spool valve, size 6. M identifies the hydraulic symbol and 6X the component-series family. The spring-return or spring-centered arrangement applies. E after the slash identifies the high-power wet-pin solenoid with detachable coil. G24 is 24 V DC, N9 is the concealed manual override, and K4 is the individual electrical connection. The standard seal version without an added /V suffix uses NBR seals.

Technical specifications

Catalog pressure limits are 350 bar at P, A and B, and 210 bar at T for the DC version. N9 manual override operation is limited to a tank pressure of 50 bar and has no assigned safety function. Select the operating point using the actual flow path, pressure and fluid conditions.

The standard NG6 DC series has a catalog flow ceiling of 80 L/min. This is not a rated flow at every pressure for 4WE6M6X/EG24N9K4. Verify the exact spool performance curves, return pressure and pressure drop for the required flow. The maximum pressure and series flow ceiling are not a simultaneous operating guarantee.

Selection and installation

• Match the full type code, material number, spool function and all additional suffixes.
• Check the NG6 manifold pattern, port arrangement and installation dimensions.
• Confirm 24 V DC control, 2 solenoids, K4 mating connectors and the required de-energized behavior.
• Provide P/A/B and tank pressures, working flow, oil type, temperature and filtration conditions.
• Confirm mating connectors, subplate, mounting screws and other accessories separately.
• Check the force and movement caused by connecting pressure to both actuator ports, including unequal cylinder areas.

Frequently asked questions

Does the M center block pressure to the actuator?

No. P, A and B communicate at center and T is blocked. Supply pressure can therefore act on both actuator ports. An unequal-area cylinder can develop a net force, so check the circuit before selecting this spool.

Are electrical plugs and a subplate included?

K4 specifies the valve electrical interface. Mating connectors are ordered separately; confirm plugs, subplate, mounting screws and other accessories in the quotation.

Can this valve always deliver 80 L/min?

The standard NG6 DC series has a catalog flow ceiling of 80 L/min. This is not a rated flow at every pressure for 4WE6M6X/EG24N9K4. Verify the exact spool performance curves, return pressure and pressure drop for the required flow. The maximum pressure and series flow ceiling are not a simultaneous operating guarantee.

What is needed to confirm price and availability?

Send the full identification, quantity, destination, operating requirements and desired supply condition. Price, availability, delivery and warranty terms will be confirmed in the quotation.
