Description

The larger the cylinder, the more a delayed pilot stage shows up in positioning accuracy. The 4WRZE25W8-325-7X/6EG24EK31/F1D3M therefore drains pilot oil externally while providing 325 l/min nominal flow at 350 bar.

Benefits

325 l/min nominal flow, 870 l/min at maximum, for fast strokes on large cylinders.
External pilot oil return keeps the pilot stage clear of back pressure in the working return.
Internal pilot oil supply cuts the piping work by one line.
A 4 ... 20 mA current command for robust signal transmission over long distances.
The integrated pressure reducing valve protects the pilot stage, valve mass 20.72 kg.

Applications

Intended for forming presses, lift tables and test rigs with high oil demand and a long return path. Spool symbol W8 provides defined behaviour in centre position. UKCA conformity, NBR seals, HL hydraulic fluid.

Manufacturer

Bosch Rexroth, material number R901004115. Two manufacturer documents exist, and the data sheet covers characteristic curves and pilot pressure data.
