LFA25 D-7X/F

The LFA25 D-7X/F control cover belongs to the LFA 2 Way Control Covers series from Bosch Rexroth and is used to direct flow in hydraulic automation circuits. A nominal size of 25 matches corresponding subplates so passage areas remain balanced for rated flow. Maximum operating pressure is 420 bar, allowing the cover to survive high-pressure power units without structural modification. Compatibility with hydraulic fluids that meet DIN 51524 simplifies fluid selection in industrial plants. System cleanliness must stay at ISO 4406 20/18/15 to limit particulate wear inside mating valve elements. Mounting holes cut with an M6 thread let the cover be fixed securely to the manifold, and the overall metric thread standard keeps tooling uniform across installation points.

A remote control interface identified as port F lets external pilot lines actuate the two-way element without disturbing the main circuit. This port uses a G1/4 thread so standard pipe fittings attach directly. Sealing is handled by NBR elastomer rings, preventing leakage of mineral oils specified for the unit. The housing weighs 2.3 kg, light enough for single-person handling during manifold assembly. A mean time to dangerous failure of 150 years indicates very low probability of malfunction over extended service periods. These characteristics make the LFA25 D-7X/F suitable for installations where dependable switching and long-term reliability are critical.
