System compatibility

4WE10J31 belongs to Rexroth WE series directional valve family,widely used in machine tools,injection molding machines,metallurgical and general industrial hydraulic systems.This is a legacy spare part for hydraulic equipment maintenance replacement.

Function

4WE10J31 is a direct-acting electromagnetic directional valve.It controls start,stop and flow direction of hydraulic oil in hydraulic system.When solenoid energized,the spool moves to switch oil channel;when de-energized,spool returns to central position by reset spring.It adopts J spool function,P port closed at neutral position,A/B/T connected together.It realizes hydraulic actuator forward,reverse and stop control.

Installation

Mount 4WE10J31 on standard ISO4401 subplate,tighten fixing bolts.Connect solenoid coil cable and hydraulic pipeline according to hydraulic schematic.Clean pipeline before commissioning,check oil cleanliness and connection tightness.

Interface

‑Hydraulic port:P,A,B,T

‑Solenoid electrical connector

‑Optional manual override button

Circuit feature

Wet-pin solenoid design,stable switching performance,low noise,anti-vibration,strong resistance to oil pollution,suitable for harsh industrial workshop environment.

Feature

4WE10J31 is obsolete Rexroth hydraulic spare part.Typical faults:coil burnout,spool stuck,internal leakage,seal aging and oil leakage.Inspect coil resistance,spool movement and sealing surface before replacement.This hydraulic valve must match working pressure,flow rate and spool function of original system,direct substitution without inspection is not recommended.

Diagnostic

When coil damaged,spool jam or seal failure occurs,the hydraulic actuator cannot reverse or stop normally,pressure loss and oil leakage will appear.

Built‑in function:Hydraulic oil flow direction control,cylinder forward/reverse movement control,actuator stop holding,used as Rexroth hydraulic system spare replacement.

Product Brief

4WE10J31 is Rexroth size10 J spool 4/3-way electromagnetic directional valve,applied for hydraulic actuator direction control.Verify working pressure,flow requirement and spool symbol before ordering.ESD protection required during handling and installation.
