Saves the external pilot supply because pilot oil is taken internally from the pressure port. Only the return runs externally through Y. With 325 l/min nominal flow, spool symbol W6 and a ±10 V command value it serves large controlled axes up to 350 bar.

Total price
A dedicated pilot pump costs installation space and money. This valve takes its pilot oil internally from the pressure port and only needs a Y line for the return, at 325 l/min nominal flow and 350 bar operating pressure.
Benefits
- Internal pilot oil supply, so neither a separate pilot pump nor an X line is required
- External pilot return through Y keeps pilot control clear of back pressure in the tank line
- 325 l/min nominal flow against a valve maximum of 870 l/min
- Spool symbol W6, command value ±10 V, on-board electronics at 24 VDC
- Mass 20.58 kg, FKM seals, HL hydraulic fluid

Application
This configuration is the usual choice for stand-alone power units without a central pilot supply, for example on baling presses, lifting gear and machine tools. It assumes an operating pressure that stays above the required pilot pressure during motion as well. The Y line has to run to tank without back pressure.
