Genuine Bosch Rexroth R900423722, type DBDS6G1X/50: Pressure Relief Valve NG6, Pressure Stage 50 bar, 50 l/min.
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 R900423722; in Rexroth codes every character (size, pressure stage, adjustment element, options and seals) changes the part, so the type code DBDS6G1X/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.
