When pilot oil comes from a small auxiliary power unit, the supply has to be external. This valve is built that way, meters 350 l/min nominal at 350 bar through the V1 spool and works with a ±10 V command value.

Total price
A dedicated small pilot power unit keeps pilot pressure constant even when the main circuit collapses. This build with external pilot oil supply makes use of that and meters 350 l/min nominal flow through its V1 spool.
Benefits
- External pilot oil supply for feeding from a separate pilot power unit
- Internal return, so only one extra line is required
- Nominal flow 350 l/min at an operating pressure of 350 bar
- Internal spool position feedback instead of a fixed characteristic
- Command value ±10 V, V1 spool, four ports
- Weight 17.85 kg, port pattern ISO 4401-08-08-0-05
