On a test rig every millimetre of stroke counts. The 4WRTE10E1-25L-4X/6EG24ETK31/A1M releases only 25 l/min nominal flow, follows a plus/minus 10 V voltage command and needs no extra pilot lines on the manifold.

Total price
Short strokes with a defined velocity profile call for a valve that passes little oil per command step. The 4WRTE10E1-25L-4X/6EG24ETK31/A1M works with a 25 l/min nominal flow and accepts a plus/minus 10 V voltage command.
Advantages
- Nominal flow of 25 l/min in size 10 for fine resolution of axis speed.
- Plus/minus 10 V command, wired straight to closed-loop and analogue cards.
- Internal pilot oil supply and internal return, no additional lines required.
- Internal spool position feedback for repeatable characteristics over the travel.
- Operating pressure up to 350 bar, flow up to 170 l/min, spool symbol E1.
- Weight of 9.6 kg, NBR seals, 24 VDC supply voltage.
