Huade HD-ZDR6DP0: the alternative to the Rexroth ZDR6DP0 pressure reducing valve

The Huade HD-ZDR6DP0 is a direct-acting pressure reducing valve in NG6 (Cetop 3) with a fixed secondary pressure of up to 40 bar, typically used to supply pilot circuits. It is the alternative to the Rexroth ZDR6DP0, with the same ISO 4401 sandwich format.

Series cross-reference

Rexroth series	Huade series	Size / interface	Max flow	Max pressure
ZDR6DP0	HD-ZDR6DP0 (40B)	NG6 – Cetop 3	7 l/min	300 bar in, 40 bar out
ZDR6D / ZDR10D	HD-ZDR6D / ZDR10D	NG6 / NG10 sandwich	50 – 80 l/min	210 bar

Why choose it instead of the original

Stable pilot pressure from a high-pressure line, without a separate pilot pump.
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.

Frequently asked questions

Which valve replaces a Rexroth ZDR6DP0?

The Huade HD-ZDR6DP0 (series 40B): NG6, up to 300 bar inlet and a fixed secondary pressure up to 40 bar.

What is it used for?

To supply pilot circuits, such as the pilot stage of proportional or pilot-operated valves, from the main pressure line.

How do I get the equivalent code?

Send us the full Rexroth ZDR6DP0 code from the nameplate: our technical team returns the equivalent HD-ZDR6DP0 code, checked for size, version and seals.
