Bosch Rexroth LFA63DB2-7X/315 manual pressure pilot control cover

LFA63DB2-7X/315, manufacturer material number R900938230, is a Bosch Rexroth size 63 manual pressure pilot control cover. It is an individual control cover with an integrated manually adjustable pressure pilot, supplied separately from the main logic insert. The selected insert and hydraulic circuit determine whether the complete arrangement performs pressure relief or normally-open pressure reduction.

Adjustment type 2 is a hexagon adjustment with protective cap. The 315 bar pressure stage is the upper adjustment endpoint, not an individual factory setting. The minimum usable pressure is flow-dependent. The specified seals are NBR.

The permissible system pressure must be established from the cover, integrated pressure pilot, selected unloading hardware, main insert and manifold limits. An insert pressure rating must not be applied to the whole assembly. Standard reference orifices are shown in the manufacturer drawing; operational tuning and circuit connections require the applicable installation conditions.
