Total price
A valve that routes its pilot circuit internally saves two fittings and two lines during assembly. The 4WRTE25V220L-4X/6EG24ETK31/A1M uses that layout and meters 220 l/min nominal flow at operating pressures up to 350 bar.
Benefits
- Internal pilot oil supply and internal return, the manifold needs no X and Y line.
- 220 l/min nominal flow, up to 870 l/min maximum flow, operating pressure up to 350 bar.
- Internal spool position feedback for repeatable metering areas.
- Plus/minus 10 V command value, on-board electronics, 24 VDC supply voltage.
- Spool symbol V with a linear characteristic, three switching positions on four ports.
- 17.94 kg, NBR seals, ISO 4401-08-08-0-05 interface, 7-pole connector (6 + PE).
