If operating pressure drops below the pilot pressure demand, the pilot stage needs its own source. The 4WRTE16E220L-4X/6EG24K31/F1M is built with external pilot oil supply and return for exactly that, at 220 l/min nominal flow. Weight 10.98 kg.

Total price
A pilot-operated valve needs a minimum pilot pressure that the main circuit does not always provide. The 4WRTE16E220L-4X/6EG24K31/F1M therefore takes its pilot oil externally and returns it externally, while the main spool opens 220 l/min nominal flow.
Benefits
- External pilot oil supply and return, pilot stage independent of the main circuit pressure.
- 220 l/min nominal flow in size 16, up to 460 l/min maximum.
- Command value 4 to 20 mA with on-board electronics, supply 24 V DC.
- Spool symbol E, three switching positions, four ports.
- 10.98 kg weight at 350 bar maximum operating pressure, NBR seals.

Applications
External pilot routing pays off in circuits with accumulator operation or strongly varying system pressure, for example on forming presses. The X line keeps pilot pressure constant while the Y line runs to tank without pressure. The rest of the piping stays as on the internal version.
Manufacturer
