Product Overview
The Rexroth DBDS 6 K 18/200 (Material Number: R900423724) is a direct operated pressure relief valve designed for precise system pressure limitation and protection in industrial hydraulic circuits. As a member of the Rexroth DBDS series, this valve operates on a direct-acting poppet principle, where a spring-loaded poppet is held against a seat until system pressure overcomes the spring force, opening the valve to divert excess flow to the tank. The DBDS 6 K 18/200 is engineered for compact installation with a nominal size of NG6 (CETOP 3 / ISO 4401-03 size 6 interface), making it ideal for manifold mounting in space-constrained hydraulic power units and control blocks. With a pressure adjustment range up to 200 bar and a spring-loaded adjustment mechanism, this valve provides reliable, repeatable pressure control for demanding industrial applications. The “K” designation indicates the adjustment type (sleeve with hexagon and locknut), ensuring secure pressure setting retention under vibration and continuous operation.
