In continuous duty with frequent load changes, repeat accuracy matters more than peak figures. This closed-loop valve holds the spool on command value through internal position feedback, meters 220 l/min nominal at 350 bar and is driven by 4...20 mA.

Total price
Under cyclic load it is repeat accuracy that counts, not a peak figure. The internal position feedback here measures spool travel continuously and corrects it, so every cycle runs at the same 220 l/min nominal flow.
Benefits
- Internal position feedback compensates deviation during the running cycle
- Nominal flow 220 l/min at 350 bar operating pressure, up to 870 l/min through the valve
- Command value 4...20 mA, no zero drift from voltage drop along the cable
- Pilot oil supply and return internal, removing two pilot ports
- V1 spool, three switching positions, four ports
- Weight 17.96 kg on port pattern ISO 4401-08-08-0-05
