Product Overview
The Rexroth DBEM 20-51/315YG24K4M (Material Number: R900923241) is a high-performance pilot-operated proportional pressure relief valve designed for precise electro-hydraulic pressure control in demanding industrial systems. As part of the renowned Rexroth DBEM series, this valve combines a robust pilot stage with a high-capacity main stage to deliver infinitely variable pressure adjustment proportional to the electrical input signal. The integrated proportional solenoid (designated by the YG24K4M code) enables stepless pressure setting, making it ideal for applications requiring dynamic pressure regulation, soft-start/stop sequences, and precise force control. With a nominal size of NG20 and a maximum pressure rating of 315 bar, this valve serves as a critical safety and control element in hydraulic circuits, ensuring system protection while facilitating advanced closed-loop pressure control strategies.
