Benefits

Closed-loop control automatically compensates for friction and temperature variations
Reduced pressure/command characteristic curve scatter compared to the external electronics version, thanks to integrated OBE closed-loop control
Precise dynamic response, adaptable to each phase of the cycle
Fewer components in the electrical cabinet thanks to electronics integrated directly in the valve body
The ZDBEE version with external pilot drain (port Y) allows pilot circuit separation from the main circuit
Independently adjustable rise and fall ramps via integrated potentiometers

Rexroth cross-reference

Huade HD-(Z)DBE(E): the alternative to Rexroth DBE, DBEE, ZDBE and ZDBEE proportional pressure relief valves

The Huade HD-(Z)DBE(E) is a proportional pressure relief valve in NG6, in subplate (DBE) or sandwich (ZDBE) format, with external or integrated OBE electronics (DBEE, ZDBEE). It is the alternative to Rexroth DBE6, DBEE6, ZDBE6 and ZDBEE6.

Series cross-reference

Rexroth series	Huade series	Size / interface	Max flow	Max pressure
DBE6 / DBEE6	HD-DBE(E)6	NG6 – subplate	30 l/min	315 bar
ZDBE6 / ZDBEE6	HD-ZDBE(E)6	NG6 – sandwich, Y port	30 l/min	315 bar

Why choose it instead of the original

Pressure set by electrical signal: change pressure levels in the cycle without manual adjustment.
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.
