Product Overview
The Rexroth LFA32 H2-7X/F (Material No. R900912728) is a high-performance control cover engineered for use with Rexroth logic cartridge valves in industrial hydraulic systems. As part of the Rexroth LFA series, this control cover serves as the pilot control interface, enabling precise directional and pressure control of the main cartridge valve stage. The “32” designation indicates an NG32 (SAE 1.25″) size, while the “H2” functional code defines the specific pilot control configuration. The “7X” series designation reflects the component generation, ensuring compatibility with current Rexroth modular hydraulic systems. This control cover is designed to accept pilot pressure signals and direct them to the main poppet of a cartridge valve, functioning as a directional spool control element within the broader valve assembly. It is a critical component in high-pressure, high-flow hydraulic circuits where reliable switching and leak-free operation are essential.
