Bosch Rexroth LFA63DBS2-7X/400 pressure-control logic valve cover

LFA63DBS2-7X/400, manufacturer material number R900955870, is a Bosch Rexroth nominal-size 63 LFA series 7X control cover for a two-way cartridge-valve system. The DBS execution combines manual pressure adjustment with provision for electrical unloading through a separately selected directional poppet pilot valve. Adjustment type 2 is a hexagon with protective cap; the standard no-V ordering key specifies NBR seals.

The 400 bar code denotes a pressure-adjustment stage, rather than a delivered pressure setting or a complete-assembly pressure rating. The selected pilot valve pressure limit must be respected. The LC main insert, manifold cavity and electrical pilot valve require separate selection; a control cover alone does not determine main flow capacity or solenoid supply.

The selected original technical pages carry RE21050, edition 1999-02. The manufacturer diagram shows the DBS control-cover arrangement together with a separately selected pilot valve; it does not establish that the illustrated pilot valve is supplied.
