Product Overview
The Rexroth DBE 20-5X/315YG24K31A1M is a pilot-operated proportional pressure relief valve from the renowned Rexroth DBE series, engineered for precise, infinitely variable pressure control in demanding industrial hydraulic systems. This valve combines the functions of a pressure relief valve with proportional solenoid actuation, allowing stepless adjustment of system pressure in direct proportion to the electrical command signal. The DBE 20-5X series is a proven design widely deployed in applications requiring accurate pressure regulation, soft-start/stop ramping, and controlled pressure unloading. With a size 20 (NG20) mounting interface and a maximum pressure rating of 315 bar, this valve delivers reliable performance in high-pressure circuits. The integrated proportional solenoid (G24 = 24 VDC) with a nominal current of 1.5 A enables precise electro-hydraulic control, making it an ideal choice for closed-loop pressure control systems and advanced industrial automation.
