Product Overview
The Rexroth LC 32 A20D7X (Material Number: R900912589) is a high-performance two-way logic cartridge valve designed for advanced flow control and pressure regulation within demanding industrial hydraulic systems. As a core component of Rexroth’s modular valve family, this logic cartridge operates on a poppet-type, seat-sealing principle, enabling zero-leakage blocking and precise directional control when integrated into a custom manifold block. The LC 32 A20D7X is engineered for high flow capacity and fast response, functioning as a pilot-operated main stage that can be combined with cover plates and pilot valves to achieve directional, pressure, or flow control functions. Its robust construction and precision-machined seating surfaces make it an ideal solution for systems requiring reliable load holding, rapid decompression, and efficient power transmission in high-pressure industrial circuits.
