Bosch Rexroth DBE 10-37 200XYG24K4-509 is a directly operated proportional pressure relief valve in the DBE family, actuated by a 24 V DC solenoid for precise, current-to-pressure control in hydraulic circuits. The XY porting configuration indicates unloading port X with external pilot oil return Y, and the size 10 frame is consistent with Rexroth DBE valves that carry a 200 bar relief setting. The G24K4 designation denotes a 24 V DC solenoid coil that drives the proportional action. Commonly used to safeguard hydraulic circuits by capping system pressure at 200 bar.
