Product Overview
The Rexroth DBDS20 P 1X/25 (Material No. R900430311) is a direct operated pressure relief valve from the proven DBDS series, designed to limit and safeguard system pressure in industrial hydraulic circuits. As a direct acting poppet-type valve, it responds immediately to pressure surges without pilot-stage delay, making it ideal for protecting individual actuators, sub-circuits, or complete hydraulic power units. The valve is set to a nominal cracking pressure of 25 bar and features a threaded adjustment element for precise, repeatable pressure setting. Its robust housing and hardened internal components ensure stable operation, minimal internal leakage, and long service life in demanding industrial environments.
