Product Overview
The Rexroth DBEME 20-71/315YG24K31A1M (Material Number: R901353070) is a pilot-operated proportional pressure relief valve with integrated electronics, part of the Bosch Rexroth DBEME series. This valve functions as a continuously adjustable pressure control element, converting an electrical command signal into a proportional hydraulic pressure limit. The integrated control electronics (OBE) are mounted directly on the valve, eliminating the need for a separate amplifier card and simplifying system wiring. The DBEME series is designed for precise pressure regulation in demanding industrial hydraulic circuits, offering excellent repeatability, low hysteresis, and fast response to dynamic pressure commands. With a nominal size of NG20 and a maximum pressure rating of 315 bar, this valve is engineered for high-pressure applications requiring accurate, electro-proportional pressure control.

Engineering Features & Advantages
- Integrated Electronics (OBE): The on-board amplifier eliminates external control cards, reducing wiring complexity, cabinet space, and potential electromagnetic interference in the signal path.
- Precise Proportional Pressure Control: The valve provides stepless pressure adjustment proportional to the electrical command signal, with low hysteresis and excellent repeatability for closed-loop pressure regulation.
- Pilot-Operated Design: The two-stage pilot-operated configuration ensures stable pressure control even at high flow rates and high system pressures up to 315 bar.
- Industrial Reliability: Constructed for continuous duty with durable, corrosion-resistant materials and proven engineering for maximum system uptime.
- Direct Fit Replacement: Precision-manufactured to original REXROTH specifications for direct replacement, minimising downtime and eliminating fitment issues.
