Product Overview
The Rexroth DBDS 30 P1A/315 (Material Number R900423715) 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 immediately to pressure surges without pilot-stage delay, opening at the set pressure to divert excess flow to the tank port and re-closing as system pressure falls. The DBDS 30 P1A/315 is designed for inline mounting with a nominal size of 30 mm and is factory preset to a cracking pressure of 315 bar, making it suitable for high-pressure circuits requiring dependable overpressure safeguarding and accurate pressure control.
