Product Overview
The Rexroth LC 32 A20E7X/- (Material Number R900906337) is a two-stage logic cartridge valve from the proven Rexroth LC series, designed for high-flow hydraulic control in industrial manifold and block systems. As a slip-in cartridge element, it functions as a pressure-compensated, pilot-operated seat valve that combines the functions of a directional, pressure, and flow control valve within a single compact cartridge. The main stage is actuated by a pilot pressure signal applied to the control chamber, allowing the poppet to open or close against system pressure with minimal leakage and excellent sealing characteristics. With a nominal size of NG32, this cartridge is engineered for high flow capacity and is typically installed in a standardized receiving bore per ISO 7368, making it an ideal building block for modular hydraulic circuits, manifold blocks, and integrated power units.
