4WE10J3X Rexroth Solenoid Directional Valve 315bar

Product Overview:

Bosch Rexroth 4WE series solenoid directional control valves (typical models 4WE10J3X/CG24N9K4, 4WE10J3X/CW230N9K4/V and compatible 4WE6 series) are direct-operated solenoid spool valves that control the start, stop and direction of hydraulic flow. Featuring wet-pin solenoids with detachable coils that can be rotated 90°, the coil can be replaced without opening the pressure-tight chamber. Porting pattern complies with ISO 4401-05-04-0-05 (CETOP 05 / NG10), available in 24 V DC or 230 V AC versions. Fully interchangeable with original Rexroth 4WE series and rigorously tested under simulated duty cycles for reliable industrial performance.

Key Technical Advantages

1. Wet-pin high-power solenoids: Coils can be replaced without opening the pressure chamber and rotated 90° for flexible installation and easy maintenance.
2. 100% drop-in interchangeability: Fully compliant with ISO 4401 and CETOP standards; identical interface and function to original Rexroth 4WE series for direct replacement.
3. High pressure and flow capability: Rated 315 bar with maximum flow of 120 L/min; precision spool design ensures low leakage and reliable switching.
4. Proven reliability through rigorous testing: High-quality cast body and wear-resistant spool, validated by 100% simulated duty-cycle testing for continuous industrial operation in demanding environments.

Application Areas

• Machine tools and injection molding machines hydraulic direction control
• Metallurgy, steel and construction machinery hydraulic circuits
• Presses, lifting platforms and material-handling equipment
• Industrial automation hydraulic systems requiring reliable solenoid directional control

Expert Maintenance Tips

Ensure hydraulic fluid cleanliness meets ISO 4406 20/18/15 or better before installation; inspect seals. Match voltage correctly (DC or AC) and rotate the coil as needed for orientation. Periodically check solenoid temperature rise and spool movement; avoid prolonged continuous energization. Coil replacement requires no system depressurization of the pressure chamber. Protect mounting surfaces during service to prevent contamination; perform functional testing and leakage checks after installation.
