Huade Hydraulics' 4WE6 series uses the same production standards as Rexroth, which can replace Rexroth directional valve 4WE6 series. Huade’s 4WE6 series is a solenoid-operated, 4-way/3-position directional control valve designed as a direct replacement for Rexroth's equivalent series. With identical porting dimensions and performance parameters, directional valve 4WE6 ensures seamless integration into existing hydraulic systems while offering 20-30% cost savings.

Advantages vs. Rexroth
✔Huade's directional valves 4WE6 can fully interchangeable with the same series offered by Rexroth, such as matching mounting dimensions, porting, and electrical connectors.
✔ Huade's directional valves 4WE6 are more cost-efficient in terms of localized production reduces lead time and pricing.
✔ Huade has strict QC inspection system, which every products will be 100% tested for leakage, pressure stability, and cycle life.
Typical Applications
Huade's diectional control vaves 4WE6 are wildly used in mobile hydraulics,industrial machinery and renewable energy systems ect.
