Frequency converters and long cable routes trouble a voltage line, while a current signal shrugs them off. The 4WRZE25W6-220-7X/6EG24EK31/F1D3M accepts a 4...20 mA command, draws its pilot oil internally and discharges it through an external return, at 220 l/min nominal flow.
Benefits
- A 4...20 mA command keeps its integrity next to converters and contactors.
- Internal pilot oil supply with external return needs only one extra line.
- Spool symbol W6 with 3 switching positions and 220 l/min nominal flow in size 25.
- A built-in pressure reducing valve holds pilot pressure constant up to 350 bar working pressure.
- UKCA conformity to SI2016/1091, NBR seals, weight 20.74 kg.
