Description

When the pilot circuit is built up completely separately, it can be filtered and monitored on its own. In version K the 4WRKE25W8-220L-3X therefore feeds and drains pilot oil externally and meters 220 l/min nominal flow at operating pressure up to 350 bar. The command value arrives as ±10 V.

Benefits

External pilot oil supply and external pilot oil return, pilot circuit can be filtered separately
Spool symbol W8, three switching positions, four ports
220 l/min nominal flow, flow rate up to 870 l/min
±10 V command value at on-board electronics, 24 V DC
18 kg weight, operating pressure up to 350 bar, ISO 4401-08-08-0-05 interface

Applications

The variant is used on power units with their own pilot pump, as commonly found in press lines and rolling mills. Well filtered pilot oil extends the service life of the pilot stage. Mounting is on a size 25 subplate.
