The fewer control lines a manifold needs, the fewer fittings can leak. This size 16 valve routes pilot oil internally in both directions, works with a ±10 V command value and releases 180 l/min nominal flow at 350 bar.

Less piping means fewer places to leak. On this pilot-operated size 16 proportional valve both pilot oil supply and pilot oil return run internally, and control is by ±10 V at 180 l/min nominal flow.
Key benefits
- Pilot oil taken and returned internally, so both external control lines disappear from the manifold.
- 180 l/min nominal flow, up to 460 l/min maximum, operating pressure up to 350 bar.
- The integrated pressure reducing valve keeps the pilot stage independent of fluctuating working pressure.
- Analog ±10 V command value, with the electronics on the valve needing only a 24 VDC supply.
- Spool symbol W6, NBR seals, 12.2 kg on an ISO 4401-07-07-0-05 pattern.

Applications
The fully internal pilot version is the standard pick for manifolds that are rarely serviced in the field. It fits presses, hoists and special-purpose machines with steady system pressure. If system pressure collapses during the cycle, a version with external pilot oil supply is the better choice.
