Product Overview
The Rexroth DBDH 10 K 18/315 (Material Number R900424183) is a direct operated pressure relief valve from the proven DBDH series, engineered by Bosch Rexroth for precise system pressure limitation and protection in industrial hydraulic circuits. As a direct acting poppet-type pressure control valve, it responds immediately to pressure surges without pilot-stage lag, making it ideal for safeguarding pumps, actuators, and downstream components against overpressure. The valve is designed for inline mounting and features a threaded cartridge-style body with a hexagon adjustment element for stepless pressure setting. With a nominal size of NG10 and a pressure rating of 315 bar, this model is factory pre-set to the specified cracking pressure and is widely deployed in demanding stationary and mobile hydraulic systems where fast, repeatable pressure control is essential.
