Metering small flows cleanly: the size 10 4WRZE10W8-25 controls a 25 l/min nominal flow through spool symbol W8 and works on a noise-tolerant 4...20 mA current command. Pilot oil supply and return run internally, so no extra line has to be laid.

On axes that move little oil, the resolution of the command input matters more than raw flow capacity. The 4WRZE10W8-25-7X handles a 25 l/min nominal flow in size 10 and accepts its command as a 4...20 mA current signal, which stays immune to pickup over long cable runs.
Benefits
- Nominal flow of 25 l/min in size 10, connection diagram ISO 4401-05-05-0-05.
- Current command 4...20 mA on on-board electronics, a broken wire stays detectable.
- Internal pilot oil supply and internal return keep the piping to the four main ports.
- A pressure reducing valve in the pilot stage holds pilot pressure independent of system pressure.
- Maximum operating pressure 315 bar, maximum flow 170 l/min.
- FKM seals, concealed manual override, UKCA declaration for electromagnetic compatibility.
