Product Overview
The Rexroth LFA 16 G-71 (Material No. R900912637) is a logic valve cover designed for use with Rexroth two-way cartridge valves in industrial hydraulic systems. As a directional control component, this cover serves as the control interface for the cartridge valve insert, housing the pilot control bores and connections that govern the opening and closing of the main poppet. The LFA series cover functions as a pilot-operated directional element, enabling precise switching, pressure holding, and flow direction control within the hydraulic circuit. Manufactured by Bosch Rexroth to exacting tolerances, this cover is a direct-fit replacement component for standard size 16 cartridge valve assemblies, ensuring reliable integration into existing manifold blocks and hydraulic power units.
