Bosch Rexroth DBETR-10 315 Proportional Pressure Relief Valve

The Bosch Rexroth DBETR-10 315 is a directly operated proportional pressure relief valve that limits hydraulic system pressure by proportionally adjusting flow in response to an electrical command. As part of the DBET family, the valve provides compact, low-volume relief control for precise pressure management in industrial hydraulics. Key verified specifications include a maximum operating pressure of 315 bar, a line volume under 20 cm3, and a flow capacity of 0.8 L/min (Q = 0.8 L/min). The DBETR-10 configuration aligns with documented DBET(E) variants, which are described for pressure ratings around 315 bar and up to 350 or 420 bar in the broader family. Because this is a directly operated valve, relief action occurs directly from the input signal without a separate pilot stage, enabling predictable, repeatable response across changing loads. This combination of small line volume, modest flow, and solid 315-bar capability makes DBETR-10 a suitable choice for protecting hydraulic circuits and maintaining a stable set pressure where precise relief control is essential.
