If the pilot circuit runs on its own pressure, the main stage has to take pilot oil from outside and return it externally. This version of the size 35 4WRKE does exactly that and meters 1000 l/min nominal flow at 350 bar from a 4 to 20 mA signal. The valve weighs 55 kg.

In systems with a dedicated pilot power unit the main stage should switch independently of the working circuit pressure. The 4WRKE35W6-1000P-3X/6EG24K31/F1D3M therefore takes its pilot oil externally and returns it externally while metering 1000 l/min nominal flow at 350 bar.
Benefits
- External pilot oil supply and external pilot oil return - the pilot stage stays operational even with a decompressed main circuit.
- 1000 l/min nominal flow in size 35 at 350 bar operating pressure, up to 3000 l/min by design.
- 55 kg weight, roughly 14 kg less than the internally piloted versions of the same series.
- Command value 4 to 20 mA through a 7-pole connector (6 + PE) to EN 175201-804, supply 24 V DC.
- Symbol W6 with a linear characteristic including fine control range and internal spool position feedback.
