In electrically noisy surroundings the current command is the safe choice. The 4WRZE25W8-325-7X accepts 4...20 mA, meters 325 l/min nominal flow with it and works up to 350 bar operating pressure without any external pilot line being laid.
Benefits
- Current command 4...20 mA, cable length and voltage drop stay uncritical.
- Nominal flow of 325 l/min in size 25, up to 870 l/min maximum.
- Internal pilot supply and internal return keep the piping to P, A, B and T.
- Build without a pressure reducing valve in the pilot stage.
- FKM seals and a mass of 21.16 kg, maximum operating pressure 350 bar.
- UKCA declaration for electromagnetic compatibility to SI2016/1091.
