Total price
High throughput and controlled position are not mutually exclusive here, since this valve combines 350 l/min nominal flow with internal spool position feedback. Pilot oil is both supplied and returned internally.
Benefits
- Nominal flow 350 l/min with closed-loop spool position rather than open-loop control
- Fully internal pilot oil routing, no extra piping on the manifold
- Command value 4...20 mA, a broken wire is detected at zero current
- Operating pressure 350 bar, up to 870 l/min through the valve
- V1 spool, three switching positions, four ports
- Weight 17.8 kg, 24 VDC supply through a 7-pole (6 + PE) connector
