Product Overview
The Rexroth LC 25 A05E74 (Material No. R900912576) is a two-stage logic cartridge valve designed for high-pressure hydraulic control in industrial systems. Manufactured by Bosch Rexroth, this valve functions as a pilot-operated, normally closed (A05E74) cartridge element that mounts into a standardized cavity block. When combined with a suitable pilot control cover, it performs directional, pressure, or flow control functions within a hydraulic circuit. The LC series is engineered for high flow capacity with minimal pressure drop, making it a reliable choice for demanding industrial applications requiring precise control of large hydraulic flows.
