When the tank line carries back pressure, the pilot oil return belongs outside. This pilot-operated size 10 proportional directional valve is built that way, meters 50 l/min nominal flow from a 4 to 20 mA command and works up to 315 bar.

Total price
The control circuit of this pilot-operated proportional directional valve takes its oil internally but returns it externally. At 50 l/min nominal flow in size 10 and up to 315 bar operating pressure, the pilot stage stays independent of back pressure in the main return.
Benefits
- Internal pilot oil supply with external return, independent of back pressure in the tank gallery.
- 50 l/min nominal flow, up to 170 l/min maximum flow in size 10.
- Linear characteristic curve with fine control range and internal spool position feedback.
- 4 to 20 mA command value with on-board electronics and 24 VDC supply.
- 315 bar maximum operating pressure, 8.4 kg weight, NBR seals.
