Bosch Rexroth R900938133 Hydraulic Cartridge Logic Valve

Bosch Rexroth R900938133 is the LFA40KWA-71 hydraulic cartridge logic valve—a 2-way cartridge valve in Rexroth’s LFA family with an integrated logic cover and designed for Du40 (40 mm) porting. It mounts in standard Rexroth cartridge cavities to deliver logic-controlled flow within compact hydraulic circuits, enabling a logic-enabled valve stack without separate manifolds. The LFA40KWA-71 (also referenced as LFA40KWA-7X in catalog variants) denotes compatibility with Rexroth’s LFA logic-cover configurations used to add centralized control to a basic two-way valve. This part number uniquely identifies the specific logic-capable assembly within Rexroth’s catalog, making it suitable for automation equipment and machine tools where space is at a premium and modular valve blocks are preferred. In practice, it serves applications that require compact directional control with integrated logic in hydraulic systems, offering the reliability and interchangeability typical of Bosch Rexroth cartridge components.
