Product Description

Product Overview

The 4WE6J62/EG24N9K4, 4WE6E-50/AW220NZ5L and variants with spools D, E, H, J, G are Bosch Rexroth 4WE6/4WE10 series direct-operated solenoid directional valves. Featuring wet-pin solenoids with spring centering or return, they control the start, stop and direction of hydraulic flow. Size NG6 offers maximum operating pressure of 350 bar and maximum flow of 80 L/min (DC). Fully compliant with ISO 4401 mounting standards, these valves provide true interchangeability as drop-in replacements for original Rexroth units without manifold modifications. Every valve undergoes precision machining and 100% simulated duty-cycle testing to ensure reliable shifting, low leakage and long service life.

Key Technical Advantages:

  1. Wet-pin solenoid design – Coils can be replaced under pressure, providing low temperature rise, extended life and good environmental protection.
  2. High-pressure high-flow capability – 350 bar operating pressure and 80 L/min flow meet the majority of industrial hydraulic requirements.
  3. True interchangeability and standard interfaces – Fully compliant with ISO 4401 mounting pattern, enabling direct replacement of original Rexroth valves and minimizing modification costs.
  4. Precision machining and reliable spring return – High-accuracy spool fit ensures dependable shifting, verified by 100% duty-cycle testing.

Application Areas:

Ideal for injection molding machines, die-casting equipment, machine tools, hydraulic power units, mobile machinery, metallurgical plants and any industrial hydraulic system requiring reliable directional control.

Expert Maintenance Tips:

Ensure the manifold surface is flat and clean and tighten bolts to the specified torque; confirm voltage match and proper earthing before wiring; maintain fluid cleanliness at ISO 4406 20/18/15 or better; periodically check solenoid temperature rise and shifting action; after prolonged storage, energize the valve to verify free spool movement.
