Bosch Rexroth material number R900424163 is the DBDS15G1X/200 Pressure Relief Valve NG15, Pressure Stage 200 bar, 235 l/min (size 15, 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 R900424163; in Rexroth codes every character (size, pressure stage, adjustment element, options and seals) changes the part, so the type code DBDS15G1X/200 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.
Before you replace it
- Seal material
- Size and connection (subplate, threaded body or cartridge cavity)
- Maximum flow of the circuit
