Product Overview
The Rexroth DBDS 6 P1A/315 (Material Number: R900423730) is a direct operated pressure relief valve from the proven DBDS series, engineered by Bosch Rexroth for precise system pressure limitation and protection in industrial hydraulic circuits. As a direct acting poppet-type valve, it responds instantaneously to pressure surges without pilot-stage lag, making it ideal for applications requiring fast, reliable overpressure protection. The valve limits the operating pressure of a hydraulic system to a preset value by discharging excess fluid to the tank when the set pressure is reached, thereby safeguarding pumps, cylinders, motors, and downstream components from damaging pressure spikes. With a size 6 (NG6) CETOP mounting interface and a pressure rating of 315 bar, the DBDS 6 P1A/315 is a compact, high-performance solution for demanding industrial pressure control tasks.
