In plants full of variable frequency drives, a voltage command picks up interference quickly. This version of the 4WRTE10W8-100L works on 4...20 mA, releases a 100 l/min nominal flow and returns pilot oil externally.

Drive cabinets with frequency converters couple interference into analogue signal lines. The 4WRTE10W8-100L-4X/6EG24EK31/F1M therefore takes its command as a 4...20 mA current and converts it into up to 100 l/min nominal flow.
Advantages
- Current command 4...20 mA, signal level stays unchanged over the cable length.
- Nominal flow of 100 l/min, up to 170 l/min with the spool fully open.
- Internal pilot oil supply with external return so back pressure never loads the pilot stage.
- Operating pressure up to 350 bar, spool symbol W8, three switching positions.
- 7-pole connector (6 + PE) to EN 175201-804 on the on-board electronics.
- Weight of 8.54 kg, NBR seals, HL hydraulic fluid.

Applications
Usual installation places are power units next to converter cabinets and mobile equipment with long looms. Internal pilot supply keeps the piping small as long as pressure at P stays above the pilot demand. Port Y has to be provided on the manifold for the return.
