Bosch Rexroth LFA63GWA-71 A18P18 Hydraulic Cartridge Valve

The Bosch Rexroth LFA63GWA-71 A18P18 Hydraulic Cartridge Valve is a compact, two‑way hydraulic cartridge valve designed for direct installation in modular block systems. It belongs to the LFA63 family and uses an LFA control cover (GWA variant) to configure directional flow within a single cartridge assembly, enabling flexible, space‑saving circuit design. The variant is cataloged as R900961388 (LFA63GWA-71/A18P18), and it is designed to fit ISO 7368 cavities, aligning with Rexroth’s standard LC/LFA cartridge layouts for seamless integration with other components. The GWA designation specifies the control cover configuration that provides actuation and flow‑control capabilities inside the cartridge, supporting compact, high‑density hydraulic circuits. Typical applications include automated machinery, tooling and clamping systems, and other industrial hydraulics where precise directional control is required in tight spaces. This valve is part of Rexroth’s modular system, allowing designers to mix LC cartridge valves and LFA logic covers to realize customized hydraulic functions in a single, compact valve block.
