A separate pilot circuit keeps the pilot stage steady when working pressure collapses with each cycle. The 4WRKE16R3-220L-3X/6EG24K31/A1D3M uses external supply and external return, controls 220 l/min nominal flow and passes up to 460 l/min.

Total price
Large forming axes draw so much oil during a load change that system pressure dips briefly. The 4WRKE16R3-220L-3X/6EG24K31/A1D3M therefore takes pilot oil externally and returns it externally, at 220 l/min nominal flow in size 16.
Benefits
- External pilot oil supply and external return, independent of working pressure.
- 220 l/min nominal flow at a throughput of up to 460 l/min.
- Symbol R3 with a linear characteristic, three switching positions across four ports.
- Command value ±10 V, electronics on the valve, 24 V DC supply.
- 350 bar maximum operating pressure in size 16, connection diagram ISO 4401-07-07-0-05.
- 11.3 kg, NBR seals, hydraulic fluid HL.
