Between fully internal and fully external pilot routing lies the practical middle path. The 4WRZE16W8-180-7X/6EG24N9EK31/A1M takes control oil internally from P, drains it through Y to the outside and controls 180 l/min nominal flow at operating pressures up to 350 bar.
Benefits
- Internal pilot oil supply with external return through Y, which removes one feed line.
- 180 l/min nominal flow in size 16 against a series maximum flow of 460 l/min.
- Spool symbol W8, 3 switching positions, version without a pressure reducing valve.
- Plus or minus 10 V command at the on-board electronics with electrical position feedback.
- Concealed auxiliary actuation, NBR seals, weight 11.72 kg, UKCA conformity.

Applications
The version is used on power units with a return filter or cooler whose T port carries back pressure. Because pilot return goes to tank separately, switching time stays even. 180 l/min nominal flow covers medium cylinders at normal cycle times.
