Close to drives and welding equipment an analogue signal line often carries more interference than useful signal. A 4...20 mA current command holds up better, and this 4WRZE25 turns it into 220 l/min nominal flow.
Benefits
- The 4...20 mA current interface is less sensitive to coupled interference than a voltage line.
- UKCA entry for electromagnetic compatibility to SI2016/1091.
- External pilot oil supply and external drain keep control circuit and working circuit apart.
- Nominal flow 220 l/min with spool symbol W8, operating pressure up to 350 bar.
- On-board electronics, 24 VDC, 7-pole connector (6 + PE), mass 20.26 kg.
