Positioning accuracy comes from a valve that knows its own spool position. The internal position feedback in this valve measures spool travel and corrects it, so 220 l/min nominal flow is released linearly and repeatably.
Benefits
- Internal spool position feedback for high control accuracy and low hysteresis
- Linear relationship between command value and flow, nominal flow 220 l/min
- Command value 4...20 mA, immune to interference over long cable runs
- Operating pressure 350 bar, up to 870 l/min through the valve
- Internal pilot oil supply with external return, only one extra line needed
- Weight 17.92 kg, port pattern ISO 4401-08-08-0-05
