Total price
A dedicated pilot drain pays off whenever the returns of several axes merge. The 4WRZE25W9-220-7X/6EG24N9EK31/F1D3M takes pilot oil internally, discharges it through its own port and works with a command value of 4 to 20 mA.
Benefits
- Internal pilot oil supply with external return, insensitive to back pressure in the tank line.
- Current command value 4 to 20 mA for interference resistant transmission over long cables.
- 220 l/min nominal flow, 870 l/min maximum, operating pressure up to 350 bar.
- Pressure reducing valve in the pilot circuit and concealed auxiliary actuation.
- Symbol W9 with three switching positions, weight 20.58 kg, NBR seals.

Applications
The valve works in plants where several consumers share one return line and tank pressure therefore fluctuates. Its own pilot drain keeps piloting apart from that. At 20.58 kg this version is among the lighter ones within size 25.
