Product Overview
The Rexroth LC 50 A40E7X (Material Number: R900929935) is a high-performance two-stage logic cartridge valve designed for demanding industrial hydraulic systems. As part of the Rexroth LC series, this valve functions as a pilot-operated, pressure-compensated seating valve that provides reliable directional, pressure, and flow control when integrated with a suitable control cover. The LC 50 A40E7X features a size 50 cartridge insert with a 40 mm nominal diameter and belongs to the 7X series (component series 70 to 79), ensuring compatibility with the latest generation of Rexroth control covers. Its robust poppet-and-sleeve design delivers zero-leakage sealing in the closed position, making it ideal for load-holding, isolation, and high-pressure switching functions in complex hydraulic circuits.
