The Rexroth ZDR6DB2-4X/210YM (material no. R900463269) is a genuine Bosch Rexroth pressure reducing valve: size 6, P2 → P1, with mechanical actuation.
The reducing valve holds a constant secondary pressure regardless of changes in the main pressure; the pressure stage in the type code sets the adjustment range.

Compatibility and replacement
Order with the 10-character material number R900463269; in Rexroth codes every character (size, pressure stage, adjustment element, options and seals) changes the part, so the type code ZDR6DB2-4X/210YM on the nameplate should match exactly.
If the nameplate of the old part is unreadable, send us a photo of the part or the machine hydraulic diagram and we will identify the matching Rexroth material number.
