When neither pilot oil supply nor pilot oil return should be piped externally, version ETK works entirely internally. It meters 350 l/min nominal flow at up to 350 bar and follows a 4...20 mA current command value.

Total price
Every extra pilot line on the manifold costs space and adds another potential leak. In version ETK the 4WRKE25E1-350L-3X takes pilot oil internally and returns it internally, so only P, T, A and B have to be piped. It still provides 350 l/min nominal flow and operating pressure up to 350 bar.
Benefits
- Internal pilot oil supply and internal pilot oil return, only four lines on the manifold
- 350 l/min nominal flow, flow rate up to 870 l/min
- Operating pressure up to 350 bar, spool symbol E1
- On-board electronics, 4...20 mA command value, 24 V DC supply
- 17.98 kg weight, ISO 4401-08-08-0-05 connection diagram

Applications
A sensible choice on compact control manifolds where several valves sit side by side and no room is left for pilot lines. The tank line has to remain largely free of back pressure. Three switching positions allow travel in both directions and a defined centre.
