Product Overview
The Rexroth LC 40 B10E7X (Material No. R900938005) is a high-performance two-stage logic cartridge valve engineered for demanding industrial hydraulic systems. As a directional control element, this poppet-type cartridge valve functions as a pilot-operated seat valve, enabling precise directional control, pressure holding, and load-holding functions within manifold block circuits. The LC series is designed to be installed into a standardized receiving bore, providing a compact, leak-free solution for high-flow directional control. With a nominal size of NG40, this valve is suited for applications requiring reliable switching and sealing performance under high pressure. Its two-stage design allows for low pilot pressure actuation while managing significant main-stage flow, making it a critical component in complex hydraulic manifolds and integrated power units.
