LFA80E-6X/CA40DQ6G24F

The LFA80E-6X/CA40DQ6G24F control cover belongs to the LFA 2 Way Control Covers series from Bosch Rexroth and is used to manage directional flow in automated hydraulic manifolds. It supports a maximum operating pressure of 420 bar so it can handle high-pressure circuits common in pressing or injection machinery. The design accepts mineral oil fluids classified as HL, HLP, HLPD, HVLP, or HVLPD, allowing integration with standard industrial reservoirs. A viscosity range of 2.8 to 500 mm²/s gives the cover stable response from startup to full operating temperature. Hydraulic fluid may enter at temperatures from −30 to +80 °C, which permits outdoor or unconditioned installations. The specified cleanliness class of ISO 4406 20/18/15 limits particle contamination, reducing wear on the mating spool.

Flow regulation is based on a 2:1 area ratio between pilot and main stages, enabling proportional pressure modulation with modest pilot force. The monitored spool position pressure of 400 bar provides feedback to ensure the valve closes securely before reverse flow occurs. An NBR seal set isolates high-pressure passages and resists mineral oil attack, maintaining leak-free performance under continuous cycling. The assembly weighs 27.0 kg, giving it enough mass to absorb hydraulic shocks without additional damping plates. These characteristics allow the LFA80E-6X/CA40DQ6G24F to serve in automated clamping blocks and power units that demand compact two-way covers with reliable high-pressure operation.
