Product Overview
The Rexroth DBEM10-71/200YG24K4M (Material Number: R901335400) is a high-performance proportional pressure relief valve designed for precise electro-hydraulic pressure control in demanding industrial systems. As part of the Rexroth DBEM series, this valve functions as a pilot-operated pressure relief valve with proportional solenoid actuation, enabling stepless adjustment of system pressure in direct proportion to the electrical command signal. Unlike fixed-setting relief valves, the DBEM10-71/200YG24K4M allows continuous, dynamic pressure regulation via an analog or PWM input, making it ideal for applications requiring variable pressure profiles, soft-start/stop sequences, or closed-loop pressure control. The valve is engineered for subplate mounting in accordance with ISO 6264 (size 10), ensuring drop-in compatibility with standard manifold and subplate interfaces. With a nominal pressure rating of 200 bar and a maximum flow capacity of 71 L/min, this proportional valve delivers reliable, repeatable performance in hydraulic power units, presses, injection molding machines, and other precision-driven industrial equipment.
