HD-2FRE SERIES
The HD-2FRE series by Huade is a 2-way proportional flow control valve with integrated pressure compensation. Flow rate is regulated continuously and proportionally to the electrical command signal — from 0 to 100% — independently of pressure variations in the circuit.

Huade HD-2FRE: the alternative to Rexroth 2FRE proportional flow control valves
The Huade HD-2FRE is a 2-way proportional flow control valve with integrated pressure compensator and closed-loop control of the metering orifice. It is the alternative to Rexroth 2FRE6, 2FRE10 and 2FRE16: the flow stays constant even when the load pressure changes.

| 2FRE16 | HD-2FRE16 | NG16 | 160 l/min | 210 bar |
Why choose it instead of the original
- Load-independent speed control with position feedback on the orifice: precise, repeatable actuator speeds.
- 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 maximum flow
- Electronics and command signal
- Mounting interface
- Seals: NBR or FPM

Frequently asked questions
Which valve replaces a Rexroth 2FRE?
The Huade HD-2FRE, in sizes 6, 10 and 16, up to 160 l/min and 210 bar, with integrated pressure compensator.
Why a pressure compensator?
It keeps the pressure drop across the orifice constant, so the flow, and the actuator speed, do not change with the load.
How do I get the equivalent code?
Send us the full Rexroth 2FRE code from the nameplate: our technical team returns the equivalent HD-2FRE code, checked for size, version and seals.
