Benefits
- Setting range 4 to 280 bar, one frame size for different operating points.
- Up to 400 l/min at 350 bar maximum operating pressure.
- Pilot-operated seat valve with internal hexagon and protective cap against accidental change.
- Electrical unloading through the solenoid at 24 VDC.
- CE conformity, 5.38 kg, subplate mounting to ISO 6264-08-13 in size 25.
