The Rexroth DBDS6P1X/50 (material no. R900423732) is a genuine Bosch Rexroth pressure relief valve: size 6, P → T, with mechanical actuation.
Direct-operated relief valves of the DBD type are the basic safety element of a hydraulic circuit; the pressure stage in the type code defines the highest pressure the valve can be set to.

Compatibility and replacement
Order with the 10-character material number R900423732; in Rexroth codes every character (size, pressure stage, adjustment element, options and seals) changes the part, so the type code DBDS6P1X/50 on the nameplate should match exactly.
The values in the table come from the official Bosch Rexroth product data. If your old part shows a different series index (for example 5X instead of 6X), send us a photo and we will confirm the current equivalent.
Replacement checklist
- Pressure stage (maximum setting)
- Size and connection (subplate, threaded body or cartridge cavity)
