Overview

The Rexroth 4WE10Y5X/EG24N9K4/M identifies an NG10, component-series 5X directional valve with spool symbol Y. 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 NG10 Y default routing

The Y configuration has a spring-return position a that connects P to B and A to T. When energized, position b connects P to A and B to T. This rest-state flow direction differs from the ordinary D spring-return configuration. Check which actuator line is connected to each work port and confirm the machine sequence together with the NG10 mounting pattern.

Key configuration details

Four main ports and 2 switching positions; spool symbol Y.
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 4401-05-04-0-05.
NBR seals for the specified catalog configuration.

Configuration code

4WE10 denotes a four-port solenoid-operated directional spool valve, size 10. Y identifies the hydraulic symbol and 5X the component-series family. Y uses positions a and b, with spring return to a. 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 /M suffix specifies NBR seals.

Seals	NBR (/M)
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	160 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 NG10 DC series has a catalog flow ceiling of 160 L/min. This is not a rated flow at every pressure for 4WE10Y5X/EG24N9K4/M. 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 NG10 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

Which flow path applies when the Y coil is de-energized?

The spring selects position a, connecting P to B and A to T. Energizing the solenoid selects position b, connecting P to A and B to T. Confirm the required actuator direction and port assignments; there is no neutral center position.

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 160 L/min?

What is needed to confirm price and availability?
