Total price
Less piping plus an interference-proof signal, that is the combination of internal pilot oil routing and a 4...20 mA command value. The W6 spool handles 220 l/min nominal flow, and up to 870 l/min can pass through the valve.
Benefits
- Pilot oil supply and return both internal, which removes two fittings from the manifold
- Command value 4...20 mA, a broken line shows up immediately as missing current
- Nominal flow 220 l/min at operating pressures to 350 bar
- On-board electronics, 24 VDC supply through a 7-pole (6 + PE) connector
- Three switching positions and four ports to ISO 4401-08-08-0-05
- Weight 20.66 kg, NBR seals, HL hydraulic fluid
