Product Overview
The Rexroth DBDS 6 K 18/100 (Material Number R900423723) 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 NG6 and a pressure adjustment range up to 100 bar, this valve is engineered for compact hydraulic power units, machine tool systems, and general industrial applications requiring dependable pressure control. The DBDS series is widely recognized for its robust construction, minimal pressure override characteristics, and consistent performance across demanding operating conditions.
