Bosch Rexroth material number R900424166 is the DBDS15G1X/400 Pressure Relief Valve NG15, Pressure Stage 400 bar, 235 l/min (size 15, 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 R900424166; in Rexroth codes every character (size, pressure stage, adjustment element, options and seals) changes the part, so the type code DBDS15G1X/400 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.
What to check first
- Pressure stage (maximum setting)
- Adjustment element
- Size and connection (subplate, threaded body or cartridge cavity)
