Long cable runs in a rolling mill do not suit a voltage signal. The 4WRTE27W6-500L-4X/6EG24K31/F1M therefore takes its command value as a current of 4 to 20 mA and meters 500 l/min nominal flow in size 27, with both pilot oil paths routed externally.

Total price
In steel plants many metres of cable sit between cabinet and valve, and a voltage signal picks up noise along the way. The 4WRTE27W6-500L-4X/6EG24K31/F1M works with a 4 to 20 mA current command instead and controls 500 l/min nominal flow at 270 bar operating pressure.
Benefits
- A 4 to 20 mA current command stays immune over long cables, unlike a voltage signal.
- External pilot oil supply and external return keep the pilot stage separate from the working circuit.
- Nominal flow 500 l/min, maximum 1000 l/min, covers large cylinders in size 27.
- Spool symbol W6 with 3 switching positions and internal spool position feedback.
- Connection diagram ISO 4401-08-07-0-05, 4 ports, NBR seals, weight 19.5 kg.
- Supply 24 V DC through a 7-pole connector (6 + PE) according to EN 175201-804.

Applications
The valve positions screw-down cylinders on rolling stands, swing drives on manipulators and lifting axes in metallurgical plants. The current command allows a long distance between control room and power unit. Both pilot oil paths run outside, so the pilot stage can use its own circuit.
