Small feed movements call for small oil volumes per command step. This size 10 4WRZE works with 25 l/min nominal flow, spool symbol W8 and a plus/minus 10 V command value. Pilot oil supply and return run internally, so no extra pilot lines are needed.

Total price
A feed slide that advances in tenths of a millimetre needs a valve that releases little oil per command step. The 4WRZE10W8-25-7X/6EG24N9ETK31/A1D3V handles 25 l/min nominal flow on the ISO 4401-05-05-0-05 interface and takes its command value as plus/minus 10 V.
Benefits
- 25 l/min nominal flow, so every command step moves correspondingly little oil.
- Plus/minus 10 V command value fed straight from the analogue card to the on-board electronics.
- Internal pilot oil supply and internal return, no additional pilot lines to plumb.
- Operating pressure up to 315 bar, flow up to 170 l/min with the spool fully open.
- Spool symbol W8 with three switching positions on four ports.
- 8.48 kg, FKM seals, 7-pole connector (6 + PE) to EN 175201-804, UKCA conformity.

Application
The valve fits infeed axes, tool slides and clamping units that have to reach positions accurately. Internal pilot supply saves plumbing inside the manifold. Fast rapid-traverse axes with high oil demand are better served by a higher flow rating.
