Total price
A second pressure reducing valve in the pilot stage adds nothing when the plant already regulates its pilot pressure. This version therefore does without one and transfers 220 l/min nominal flow at 350 bar.
Benefits
- Without a built-in pressure reducing valve, matched to plants with an already regulated pilot pressure.
- 220 l/min nominal flow at 350 bar, flow up to 870 l/min in size 25.
- External pilot oil supply and external return for a self-contained pilot circuit.
- 4 to 20 mA command value on the on-board electronics, internal spool position feedback.
- Spool symbol W6, 20.58 kg, UKCA declaration for electromagnetic compatibility.
