Product Overview
The Rexroth LC 25 A40E74 (Material Number: R900912574) is a high-performance two-way logic cartridge valve engineered for demanding industrial hydraulic systems. As part of the Rexroth LC series, this poppet-type cartridge valve functions as a pilot-operated, pressure-compensated seating valve designed for directional, pressure, and flow control functions when integrated into a custom manifold block. The LC 25 A40E74 features a size 25 cavity and is actuated via a pilot pressure signal applied to the control chamber, allowing it to function as a directional spool element within a logic circuit. Its robust construction and precision-machined seating geometry deliver reliable, leak-free operation in high-pressure circuits, making it a critical component in modern hydraulic power units and manifold-based control systems.
