Product Overview
The Rexroth LC32DB40DK80/420N (Material Number: R901587432) is a high-performance two-stage logic cartridge valve designed for demanding industrial hydraulic systems. As a directional control element, this valve functions as a pilot-operated, normally closed (NC) cartridge unit that regulates flow direction and pressure within a manifold block. The “LC” series is renowned for its robust poppet and sleeve design, offering zero-leakage sealing when closed and minimal pressure drop when open. The model code indicates a size 32 cartridge with a 40 bar cracking pressure adjustment, a DK80 pilot cover, and a 420 bar maximum working pressure rating. This valve is engineered to serve as a reliable main stage control in high-pressure circuits, providing precise switching and load-holding capabilities essential for complex hydraulic machinery.
