Size 25 with a reduced nominal flow: the 4WRZE25W8-220 meters 220 l/min and takes up to 870 l/min peak throughput at 350 bar. Spool symbol W8 and the 4...20 mA current command suit long signal runs in plant engineering.

Total price
Not every axis in size 25 needs the full cross section. The 4WRZE25W8-220-7X stays at 220 l/min nominal flow and gains spool travel resolution from it, while still working up to 350 bar and passing 870 l/min at peak.
Benefits
- Nominal flow of 220 l/min with connection diagram ISO 4401-08-08-0-05.
- Spool symbol W8 with three switching positions and four ports.
- Current command 4...20 mA, unaffected by voltage drop over long cables.
- Internal pilot oil supply, external drain through a dedicated Y line.
- NBR seals and a mass of 21.5 kg, maximum operating pressure 350 bar.
- Concealed manual override for setup work without control voltage.

Application
The valve drives medium feed and lift axes, for instance on injection moulding machines, plastics presses and materials testing machines. The reduced nominal flow allows finer ramps than the full flow step of the same size. The external pilot drain calls for a Y port routed to tank without back pressure.
