Huade HD-4WRE(E): the alternative to Rexroth 4WRE and 4WREE proportional valves
The Huade HD-4WRE(E) is a direct-acting closed-loop proportional directional valve with an integrated LVDT spool position transducer, in NG6 (Cetop 3) and NG10 (Cetop 5). It is the alternative to Rexroth 4WRE (external electronics) and 4WREE (integrated OBE electronics), with the same ISO 4401 interface and 4/3 and 4/2 configurations.

Why choose it instead of the original
- Closed loop with LVDT feedback: precise, repeatable control of direction and flow, for axes, presses and test benches.
- 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
- Version: external electronics (4WRE) or on-board electronics (4WREE)
- Nominal flow and spool type
- Command signal (voltage or current) and connector
- For the external version, the driver: we supply the HD-US-DAS2 card

Frequently asked questions
Which valve replaces a Rexroth 4WREE?
The Huade HD-4WRE(E) in the version with integrated OBE electronics, in NG6 or NG10, with the same ISO 4401 mounting interface.
And a Rexroth 4WRE with external electronics?
The HD-4WRE(E) in the external-electronics version, paired with the Huade HD-US-DAS2 driver card.
Is it a closed-loop valve?
Yes: an LVDT inductive transducer integrated into the valve body measures the spool position, so the valve controls direction and flow in closed loop.
How do I get the equivalent code?
Send us the full Rexroth code: we return the equivalent HD-4WRE(E) code with size, nominal flow, spool and electronics checked by our technical team.
