Product Overview
The Rexroth DBETR-10/315G24K4M (Material Number: R900485944) is a high-performance, direct-operated proportional pressure relief valve designed for precise electro-hydraulic pressure control in demanding industrial systems. Part of the renowned Rexroth DBETR series, this valve functions as a pilot-operated or direct-acting proportional pressure limiting valve, converting an electrical current input into a continuously variable pressure setting. Unlike standard on-off valves, the DBETR-10/315G24K4M provides infinitely variable pressure regulation, allowing for smooth ramping, load holding, and system unloading without pressure spikes. With a nominal size of 10 (NG10) and a maximum pressure rating of 315 bar, this valve is engineered for applications requiring high-resolution pressure modulation, fast response times, and exceptional repeatability. The integrated 24V DC proportional solenoid (G24K4M) ensures compatibility with modern industrial control amplifiers, making it a critical component in closed-loop pressure control circuits, injection molding machines, and hydraulic test stands.
