Product Overview
The Rexroth LFA25DBW2-7X/315 is a high-performance control cover designed for use with two-way cartridge valves in industrial hydraulic systems. As part of the Rexroth LFA series, this control cover functions as a pressure control element, specifically configured for pressure reducing and pressure limiting functions when paired with a compatible cartridge valve insert. The “DBW” designation indicates a pressure reducing/relieving function, while the “7X” series denotes the component generation. The “315” suffix specifies a maximum operating pressure of 315 bar, making it suitable for high-pressure industrial circuits. This control cover mounts directly onto the cartridge valve body and provides the pilot control interface, adjustment mechanism, and pressure sensing ports required for precise pressure regulation in demanding hydraulic power units.
