Product Overview
The Rexroth LC 50 A05E70/ (Material Number R900938022) is a two-stage logic cartridge valve engineered for high-capacity flow control in industrial hydraulic systems. As a normally closed, pilot-operated cartridge element, it functions as a pressure or directional control insert that mounts directly into a standardized cavity block, eliminating the need for separate subplates and reducing manifold complexity. The LC series is a proven modular building block within Rexroth’s logic valve family, designed to handle high flow rates with minimal pressure drop while maintaining precise spool positioning through pilot pressure actuation. This cartridge valve serves as the core control element in manifold-based circuits, enabling functions such as unloading, sequencing, pressure holding, and directional flow switching in high-pressure industrial power units.
