Bosch Rexroth material number R900423715 is the DBDS30P1X/315 Pressure Relief Valve NG30, Pressure Stage 315 bar, 350 l/min (size 30, P → T, with mechanical actuation).
A pressure relief valve limits the system pressure: when the set pressure is reached, the poppet opens and returns oil to tank, protecting pumps, hoses and actuators from overload.

Compatibility and replacement
Order with the 10-character material number R900423715; in Rexroth codes every character (size, pressure stage, adjustment element, options and seals) changes the part, so the type code DBDS30P1X/315 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.
What to check first
- Adjustment element
- Pressure stage (maximum setting)
- Seal material
