Rexroth 4WE6GA6X/EG24N9K4 Solenoid Directional Valve

Overview

The Rexroth 4WE6GA6X/EG24N9K4 identifies an NG6, component-series 6X directional valve with spool symbol GA. This catalog configuration uses one solenoid with spring return. Provide the full nameplate and circuit requirements so the supplied unit can be confirmed.

Using a tandem rest position with one solenoid

GA uses positions a and 0 of the G symbol. The spring-return position 0 connects P to T and blocks A and B. Energizing the single solenoid selects position a, connecting P to A and B to T. Check the pressure drop through the P-to-T return path at the intended flow. Assess actuator holding separately because internal spool leakage remains.

Key configuration details

• Four main ports and 2 switching positions; spool symbol GA.
• 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. GA identifies the hydraulic symbol and 6X the component-series family. The A in GA selects positions a and 0 of the G 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 4WE6GA6X/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

Is GA a three-position G valve?

GA uses only positions a and 0 of the G symbol, with one solenoid. At rest, P connects to T while A and B are blocked. When energized, position a connects P to A and B to T. Specify the two-position GA code required by the circuit.

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 4WE6GA6X/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?
