Huade HD-Z2FS: the alternative to Rexroth Z2FS throttle check valves

The Huade HD-Z2FS is a sandwich-plate throttle check valve for meter-in or meter-out speed control of actuators. It is the alternative to Rexroth Z2FS6 and Z2FS10: same ISO 4401 sandwich format, stacked between the directional valve and the subplate, with throttling on A and B, on A only or on B only.

Series cross-reference

Rexroth series	Huade series	Size / interface	Max flow	Max pressure
Z2FS6	HD-Z2FS6 (series 4X)	NG6 – Cetop 3 sandwich	80 l/min	315 bar
Z2FS10	HD-Z2FS10 (series 3X)	NG10 – Cetop 5 sandwich	160 l/min	315 bar

Why choose it instead of the original

Manual throttle with free return flow: actuator speed is adjusted without extra fittings or piping.
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

Size and series (NG6 series 4X, NG10 series 3X)

Frequently asked questions

Which valve replaces a Rexroth Z2FS6?

The Huade HD-Z2FS6 (series 4X): Cetop 3 sandwich plate, up to 80 l/min and 315 bar.

Which valve replaces a Rexroth Z2FS10?

The Huade HD-Z2FS10 (series 3X): Cetop 5 sandwich plate, up to 160 l/min and 315 bar.

Does it fit my existing valve stack?

Yes. It follows the ISO 4401 sandwich format, so it stacks between the directional valve and the subplate like the original.

How do I get the equivalent code?

Send us the Rexroth code from the valve: our technical team returns the equivalent HD-Z2FS code with size, series and throttled side checked.
