Frequently Bought Together

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.
