A valve rated at 500 l/min still has to creep. Spool symbol W6 provides a fine control range around mid position for that, the command arrives as a 4...20 mA current, and operating pressure reaches 270 bar.

The 4WRKE27W6-500P-3X/6EG24ETK31/F1D3M resolves the conflict between high flow and fine metering. The curve of spool symbol W6 is linear but opens more gently around zero, so creep travel and rapid traverse run through the same valve. Pilot supply and return stay internal, and 500 l/min nominal flow is available.
Benefits
- Spool symbol W6 with a linear curve and a fine control range for creep travel.
- Nominal flow 500 l/min, maximum 1000 l/min, operating pressure to 270 bar.
- Internal pilot routing without extra X and Y lines.
- 4...20 mA current command at the on-board electronics with closed loop spool control.
- NBR seals, 19.44 kg, mounting pattern ISO 4401-08-08-0-05.
