Total price
If you need the characteristic curve of the W8 spool but not its full flow rate, the 4WRTE25W8-220L-4X/6EG24K31/F1V offers it at 220 l/min nominal flow. The reserve of up to 870 l/min stays available, the command value is a 4 ... 20 mA current, and the pilot stage works through its own X and Y lines.
Benefits
- Spool symbol W8 at only 220 l/min nominal flow, which gives finer command value resolution.
- A maximum flow rate of 870 l/min remains available as a reserve.
- Separate pilot paths through X and Y for a pilot stage independent of the working circuit.
- A 4 ... 20 mA current command value at an operating pressure of up to 350 bar.
- FKM seals, a valve weight of 18.1 kg and mounting pattern ISO 4401-08-08-0-05.
