Pressure surges in the return line disturb the pilot stage of a large directional valve. The 4WRKE27R3-500L-3X/6EG24TK31/A1D3M therefore drains its pilot oil externally while metering 500 l/min nominal flow at 270 bar operating pressure.

Total price
When several consumers share one tank gallery, the pressure there is rarely calm. The 4WRKE27R3-500L-3X/6EG24TK31/A1D3M routes its pilot oil drain externally for that reason and keeps the pilot stage clear of those fluctuations, at 500 l/min nominal flow and 270 bar operating pressure.
Benefits
- External pilot oil drain in the TK31 version decouples the pilot stage from return line pressure.
- 500 l/min nominal flow and up to 1000 l/min maximum flow in size 27.
- A ±10 V command value, on-board electronics, 24 VDC supply.
- Spool symbol R3 with three switching positions across four ports, ISO 4401-08-08-0-05 mounting pattern.
- Operating pressure up to 270 bar, 19.68 kg valve mass, NBR seals for HL hydraulic fluid.
