In metallurgical plants the pilot stage often runs on its own filtered circuit. The 4WRZE25E1-325-7X/6EG24N9K31/F1D3M takes pilot oil from outside and drains it outside while metering 325 l/min nominal flow at 350 bar operating pressure.
Benefits
- Pilot oil supply and return both external, matching separated control oil circuits.
- Nominal flow 325 l/min, plant flow up to 870 l/min in size 25.
- A 4 to 20 mA current command bridges long distances to the control room.
- Spool symbol E1 with 3 switching positions, connection diagram ISO 4401-08-08-0-05, 4 ports.
- Operating pressure 350 bar, weight 20.68 kg, UKCA conformity to SI2016/1091.
