Product Overview
The Rexroth DBEM 20-71/100YG24K4M (Material Number: R901353029) is a high-performance, pilot-operated proportional pressure relief valve designed for precise, continuous electro-hydraulic pressure control in demanding industrial systems. Part of the renowned Rexroth DBEM series, this valve combines a robust pilot stage with a high-capacity main stage, allowing for infinitely variable system pressure adjustment proportional to the electrical input signal. Unlike standard on-off relief valves, the DBEM 20-71/100YG24K4M enables smooth ramping, dynamic pressure profiling, and energy-efficient operation by matching pump output to actual load requirements. With a size 20 (NG20) mounting interface and a nominal pressure rating of 100 bar, it serves as a critical control element in complex hydraulic circuits requiring high flow capacity and exceptional repeatability.

Engineering Features & Advantages
- Precision Proportional Control: The valve spool position and resulting pressure are directly proportional to the electrical command signal, enabling infinite adjustment and precise pressure regulation without manual intervention.
- Integrated Electronics (OBE): The “K4M” designation indicates an integrated control amplifier, simplifying wiring, reducing installation space, and improving signal-to-noise immunity for reliable operation in electrically noisy industrial environments.
- High Flow Capacity with Low Pressure Drop: The size 20 main stage is optimized for high flow rates while maintaining minimal pressure loss, ensuring energy-efficient operation and reduced heat generation in the hydraulic circuit.
- Excellent Stability & Repeatability: Pilot-operated design with a damped main spool provides superior pressure stability, low hysteresis, and excellent repeatability, critical for closed-loop pressure control applications.
- Direct Fit Replacement: Manufactured to exact Rexroth dimensional and functional standards, ensuring seamless drop-in compatibility with existing DBEM series installations and original OEM specifications.
