The LFA63DBW2-7X/400/12 control cover is produced by Bosch Rexroth for the LFA 2 Way Control Covers series. It directs flow in hydraulic logic modules and integrates with cartridge valves in automated circuits. The cover mates to installations built on the ISO 7368 interface, allowing straightforward mounting onto standard cavity blocks. A nominal size of 63 establishes the internal passage dimensions and defines compatible valve cartridges. System pressure can be handled up to 420 bar, so the cover supports high-pressure motion sequences. It is suited for HL and HLP fluids according to DIN 51524 and accepts viscosities from 2.8 to 500 mm²/s.
Cleanliness of the operating medium must remain at ISO 4406 code 20/18/15 for reliable service life. Permissible fluid temperature spans −20 to +80 °C, enabling operation in both refrigerated and warm installations. The nozzle port is threaded G3/8 to accommodate pressure damping orifices. Remote control connections use an SAE-12 (1-1/16-12 UN) thread to integrate pilot lines. The housing weighs 21.0 kg, which influences manifold support requirements. Mean time to dangerous failure is rated at 150 years, reflecting robust mechanical design.
