Bosch Rexroth LFA32DBW2-7X/315 pressure pilot cover with unloading-valve interface

LFA32DBW2-7X/315, manufacturer material number R900912815, is a Bosch Rexroth size 32 pressure pilot cover with unloading-valve interface. 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 DBW cover provides a mounting interface for a separately ordered directional unloading valve. The article designation does not identify an included solenoid valve, coil voltage or complete electrohydraulic assembly. Reference drawings show alternative pilot hardware for interface planning.

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.

Technical reference: manufacturer-authored RE21050 compiled edition 2003-02, containing retained earlier page revisions. The dated reference identifies applicable component design data and does not establish current stock or an individual assembly setting.
