The 4WRKE27E1-500L-3X/6EG24EK31/F1D3M is a pilot operated proportional directional valve for high flow rates. Spool symbol E1 opens linearly, 500 l/min nominal flow is the design point and 1000 l/min the upper limit. Pilot oil comes internally from the main circuit, while the pilot stage drains externally through Y.
Benefits
- 4...20 mA command input, so even long cable routes work without level loss.
- Spool symbol E1 with a linear curve, 500 l/min nominal flow, up to 1000 l/min maximum.
- Internal pilot supply with external return through Y, independent of tank pressure.
- Operating pressure to 270 bar in size 27 on mounting pattern ISO 4401-08-08-0-05.
- NBR seals and a valve weight of 19.42 kg on a 24 VDC supply.
