For systems that need 325 l/min nominal and draw pilot oil from a separate circuit, this pilot-operated proportional directional valve in size 25 controls flow to 350 bar. Pilot oil is supplied externally and returned internally, with a ±10 V command value handled by the on-board electronics.

Total price
Where pilot oil should come from a separate filtered circuit, this version with external pilot oil supply and internal pilot return fits. Its W6 spool handles a nominal flow of 325 l/min, and up to 870 l/min can pass through the valve.
Benefits
- Nominal flow 325 l/min, roughly half as much again as the 220 l/min version of the same series
- External pilot oil supply keeps pilot control stable even when main pressure fluctuates
- Command value ±10 V processed directly by the on-board electronics
- Operating pressure 350 bar, flow through the valve up to 870 l/min
- Four ports and three switching positions to port pattern ISO 4401-08-08-0-05
- Weight 20.56 kg in a steel body sealed with NBR
