Frequently Bought Together

When control quality has to stay equal across the whole load range, the pilot circuit is separated completely from the working circuit. The 4WRZE25E1-325-7X/6EG24N9K31/A1D3V does that and adds a pressure reducing valve, at 325 l/min nominal flow and up to 350 bar.

Benefits

  • External pilot oil supply and external pilot oil return plus a built-in pressure reducing valve.
  • 325 l/min nominal flow in size 25, 870 l/min maximum.
  • ±10 V command value on 24 VDC, spool symbol E1, 3 switching positions.
  • Concealed manual override, operating pressure up to 350 bar.
  • FKM seals, ISO 4401-08-08-0-05 interface, 20.58 kg.

Applications

This version is chosen when test rigs or production lines have to deliver repeatable cycles over years. A dedicated pilot circuit and the pressure reducing valve keep the pilot stage independent of load and of the temperature drift of the system. UKCA conformity is documented.
