Product Overview
The Rexroth DBDS 10 K1X/100 (Material Number: R900424147) is a direct operated pressure relief valve designed for precise system pressure limitation and protection in industrial hydraulic circuits. As part of the Rexroth DBDS series, this valve operates on a direct-acting poppet principle, where a spring-loaded poppet responds instantly to system pressure changes, providing fast and reliable overpressure protection. With a nominal size of NG10 and a pressure setting of 100 bar, this valve is engineered for compact installation in manifold blocks or as a threaded cartridge-style component. Its direct operated design ensures minimal pressure overshoot and stable performance across a wide temperature and viscosity range, making it a trusted choice for demanding hydraulic systems requiring dependable pressure control.
