Product Overview
The Rexroth Z2DB6VC2-4X/315V (material number R900411318) is a direct-operated sandwich plate pressure relief valve designed for integration into modular hydraulic control systems. Manufactured by Bosch Rexroth, this valve functions as a pilot-operated pressure limiting device within a sandwich plate stack, providing precise system pressure regulation and overload protection. The “VC2” designation indicates a specific pressure adjustment range and spring configuration, while the “315V” rating confirms a maximum operating pressure of 315 bar. Its compact sandwich plate design allows direct mounting between a directional valve and a subplate, eliminating the need for additional piping and reducing installation complexity in high-pressure industrial circuits.
