Benefits
- Ability to handle more demanding circuits without moving to the next size up, thanks to the high-power version (size 6)
- Spool actuation possible even in the absence of electrical supply
- Reduced friction and component wear through the solenoid piston operating immersed in oil
Application fields

Huade HD-WE: the alternative to Rexroth 4WE6 and 4WE10 directional valves
If your machine uses Rexroth 4WE6 (Cetop 3) or 4WE10 (Cetop 5) solenoid directional valves, the Huade HD-WE series fits the same ISO 4401 subplates and manifolds, with the same 4/3 and 4/2 configurations and spring, detent or no-spring return. Huade has built valves under Rexroth technology licence since 1981, which is why its series carry the same designations.
Looking for the HEVH series? The HEVH has been superseded by the HD-WE: same ISO 4401 interface, so the HD-WE is the valve to order today.
Series cross-reference
| Rexroth series | Huade series | Size / interface | Max flow | Max pressure |
|---|---|---|---|---|
| 4WE6 | HD-WE6 | NG6 – Cetop 3 (ISO 4401-03) | 80 l/min | 315 bar (350 bar high-power) |
| 4WE10 | HD-WE10 | NG10 – Cetop 5 (ISO 4401-05) | up to 120 l/min | 315 bar |
| 4WE10 with T1/T2 ports | HD-5-WE10 | NG10 – Cetop 5 | 120 l/min | 315 bar |
Why choose it instead of the original
- Wet-pin solenoids in DC or AC, with manual override: the spool can be moved even without electrical supply.
- 24-month warranty and every unit tested on our test bench in Gallarate (Italy) before shipment.
- Delivery: 24–48 hours for stock items, 2 weeks standard.
- Technical support: our engineers convert your current code and check the installation with you.
What we check before confirming the replacement
- Spool symbol (centre position) and number of positions
- Coil voltage, AC or DC, and connector type
- Return type: spring, detent or no spring
- Seals: NBR for mineral oil, FPM for phosphate esters

Frequently asked questions
Which valve replaces a Rexroth 4WE6?
The Huade HD-WE6: same NG6 / Cetop 3 interface, up to 80 l/min and 315 bar, or 350 bar with the high-power solenoid.
Which valve replaces a Rexroth 4WE10?
The Huade HD-WE10, for NG10 / Cetop 5 subplates, up to 120 l/min and 315 bar. If your circuit needs separate T1/T2 tank ports, we propose the HD-5-WE10.
Do I need to change the subplate or the wiring?
No. The mounting pattern follows ISO 4401, so the valve fits the existing subplate. We match coil voltage and connector to your current installation.
How do I get the equivalent code?
Send us the full Rexroth code from the valve nameplate: our technical team returns the equivalent HD-WE code with spool, voltage and connector already checked.
