LFA63DBW2-7X/315/12

The LFA63DBW2-7X/315/12 control cover belongs to the LFA 2 Way Control Covers series and is manufactured by Bosch Rexroth. It directs hydraulic flow in cartridge valve assemblies used for automated actuation. The nominal size is 63, which sets the passage area for high-volume circuits. Its maximum operating pressure reaches 420 bar so the cover can be applied in high-pressure systems without deformation. For the individual ports a, b, x, z1, and z2 the maximum pressure is limited to 315 bar, protecting downstream components from over-loading. The cover is machined to match ISO 7368 installation bores, allowing it to fit directly into standardized cavities. A cleanliness class of ISO 4406 20/18/15 is required to prevent abrasion and valve jamming during continuous duty.

Sealing is handled by NBR material, enabling reliable fluid retention in typical industrial hydraulic fluids. SAE threads and UNC bolts are provided, simplifying assembly with widely available fasteners and port adapters. The cover has a weight of 21.0 kg so installers can handle it without lifting equipment yet still benefit from a rigid housing. A mean time to dangerous failure of 150 years supports long service intervals in safety-related circuits. These characteristics complete the functional profile needed for durable two-way cartridge valve control in automated hydraulic machinery.
