An internal pilot feed with a separate Y return keeps pilot control clear of back pressure in the tank line. With spool symbol E and 325 l/min nominal flow the valve suits large controlled axes up to 350 bar. The command input is ±10 V and the electronics are on board.

Total price
When back pressure in the tank line rises, pilot control is the first thing to suffer. This valve answers that with an internal pilot feed and a separate return through Y, while controlling 325 l/min with spool symbol E.
Benefits
- Separate pilot return through Y, independent of back pressure in the main tank circuit
- Internal pilot feed, so no dedicated pilot pump is needed
- 325 l/min nominal flow, spool symbol E, operating pressure up to 350 bar
- Command value ±10 V, on-board electronics, supply 24 VDC
- Mass 20.65 kg, subplate mounting ISO 4401-08-08-0-05

Application
This configuration proves itself on plants with long or heavily loaded tank lines where return pressure climbs noticeably. Large presses and test rigs with a shared return manifold belong in that group. The Y line has to run separately to tank without a filter or restrictor in the path.
