Overview

The Rexroth 4WE6C6X/EG24N9K4 identifies an NG6, component-series 6X directional valve with spool symbol C. This catalog configuration uses one solenoid with spring return. Provide the full nameplate and circuit requirements so the supplied unit can be confirmed.

Matching the NG6 C switching symbol

The C configuration uses one solenoid and a spring to select two working positions. At rest, position b connects P to A and B to T. Energizing the solenoid selects position a, connecting P to B and A to T. C and D have the same end-position connections, but their hydraulic transition symbols differ. Match the complete symbol and the required switching behavior when selecting this configuration.

Key configuration details

Four main ports and 2 switching positions; spool symbol C.
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. C identifies the hydraulic symbol and 6X the component-series family. C uses positions a and b, with spring return to b. The transition symbol must be checked separately from the end-position connections. 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.

Electrical connection	K4; 3-pole (2 + PE), EN 175301-803; mating connector separate
Manual override	N9; concealed
Mounting pattern	ISO 4401-03-02-0-05
Seals	NBR (standard seal version)
Maximum P, A and B pressure	350 bar; operating envelope applies
Maximum T-port pressure	210 bar for DC version; manual override limit differs
Series DC flow ceiling	80 L/min; series reference only, not a guaranteed flow rating for this spool

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 4WE6C6X/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

Can C be selected only by matching the D end positions?

The C and D symbols share the same end-position port connections but have different hydraulic transition symbols. Confirm the complete spool symbol and switching requirements before selecting a replacement. This C configuration has two positions, one solenoid and spring return to position b.

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?
