When main circuit pressure swings widely, the pilot stage should draw its oil from a source of its own. This variant of the 4WRZE25 is externally piloted for that reason, carries 325 l/min nominal flow at 350 bar and uses spool symbol E.

External pilot oil supply and external pilot oil return keep control quality independent of what the main circuit pressure does. The 4WRZE25E325-7X/6EG24K31/A1D3M meters 325 l/min nominal flow at 350 bar and switches through symbol E in three positions.

Benefits

  • External pilot oil supply and external return, steady piloting even when the main circuit is unloaded.
  • Nominal flow 325 l/min, with up to 870 l/min possible through the valve.
  • Spool symbol E with the centre position closed as defined by the associated switching symbol.
  • Operating pressure up to 350 bar on the size 25 mounting pattern ISO 4401-08-08-0-05.
  • On-board electronics for the analog ±10 V command value, 24 VDC supply.
  • 7-pole connector (6 + PE) to EN 175201-804, mass 20.62 kg.

Applications

The version fits plants whose main circuit is unloaded from time to time, for example presses with relief phases. A separate pilot circuit still holds the spool in position. Pilot supply and return must be provided on site.
