Product Overview
The Rexroth LC 25 A40E7X/V (Material Number: R900928559) 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 logic element is designed to be installed into a standardized receiving cavity, where it functions as a pilot-operated, pressure-compensated seat valve. The LC 25 A40E7X/V serves as the main stage in a logic circuit, enabling precise directional, pressure, and flow control when combined with a suitable pilot control valve and cover plate. With a nominal size of NG25, this cartridge valve is widely utilized in manifold block systems where compact installation, leak-free sealing, and high flow capacity are critical. Its robust construction and proven sealing geometry make it an ideal choice for continuous-duty industrial applications requiring reliable switching and load-holding performance.
