Rexroth 4WE6JA6X/EG24N9K4 Solenoid Directional Valve

Overview

The Rexroth 4WE6JA6X/EG24N9K4 identifies an NG6, component-series 6X directional valve with spool symbol JA. This catalog configuration uses one solenoid with spring return. Provide the full nameplate and circuit requirements so the supplied unit can be confirmed.

Specifying the JA float rest position

JA uses positions a and 0 of the J symbol. At rest, P is blocked while A and B communicate with T. Energizing the solenoid selects position a, connecting P to B and A to T. The open actuator-to-tank paths allow movement according to the external load and circuit. Check the required rest-state behavior and any separate load-control components before selecting this valve.

Key configuration details

• Four main ports and 2 switching positions; spool symbol JA.
• 1 solenoid; spring return.
• 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. JA identifies the hydraulic symbol and 6X the component-series family. The A in JA selects positions a and 0 of the J symbol, with spring return to 0. 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 4WE6JA6X/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, 1 solenoid, 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.
• Match the de-energized and energized port paths, including the hydraulic transition symbol. Directional spool valves do not provide a zero-leakage load-holding guarantee.

Frequently asked questions

What happens to A and B in the JA rest position?

In spring-return position 0, both A and B connect to T while P is blocked. External forces can therefore move the actuator according to the circuit. JA uses positions a and 0 only; energized position a connects P to B and A to T.

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 4WE6JA6X/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.
