DIRECTIONAL VALVES – SOLENOID OPERATED POPPET

HD-M-SED Series

The Huade HD-M-SED series is a line of direct solenoid-actuated seat-type directional valves, available in 3/2-way and 4/2-way configurations. The seat technology ensures leak-free sealing even at maximum operating pressures, making this type of valve the indicated solution for circuits where flow blocking must be absolute.

Huade HD-M-SED: the alternative to Rexroth M-SED6 poppet directional valves

The Huade HD-M-SED is a solenoid-operated poppet directional valve in NG6 (Cetop 3): the seat closes without leakage, so the load stays in position with the pump off. It is the alternative to the Rexroth M-SED6, with the same ISO 4401 interface.

Frequently asked questions

Which valve replaces a Rexroth M-SED6?

The Huade HD-M-SED6: NG6 / Cetop 3 poppet valve, up to 25 l/min and 350 bar.

Why a poppet valve instead of a spool valve?

Spool valves always have a small internal leakage; a poppet seat closes tightly, so the actuator does not drift under load.

How do I get the equivalent code?

Send us the full Rexroth M-SED6 code from the nameplate: our technical team returns the equivalent HD-M-SED code, checked for size, version and seals.
