Machines with their own pilot supply want a valve that takes pilot pressure from outside. This version runs on external pilot oil supply and external pilot oil return, meters 220 l/min at 350 bar and stays independent of the pressure in main port P.

Total price
If pressure in the main channel drops during start-up, an internally piloted valve loses actuating force. This size 16 version draws pilot oil through a dedicated line and keeps the spool under control in that moment, while metering 220 l/min nominal flow.
Benefits
- External pilot oil supply decouples the pilot stage from load pressure in port P.
- External pilot oil return carries leakage away without pressure and protects the pilot stage from tank back pressure.
- 220 l/min nominal flow and 460 l/min peak flow at 350 bar operating pressure.
- Spool symbol E1 with internal spool position feedback for symmetric behaviour in both directions.
- On-board electronics with ±10 V command value, interface ISO 4401-07-07-0-05, weight 11.5 kg.

Applications
External pilot supply pays off in accumulator circuits, in systems with strongly varying system pressure and wherever several valves share one pilot source. Pilot pressure also survives long idle periods between cycles. The Y return should be routed to tank without back pressure.
