The fewer lines a manifold needs, the less can leak. The 4WRTE27V1-500L-4X/6EG24ETK31/A1M therefore does without separate pilot lines, supplies itself internally and drains internally, at 500 l/min nominal flow and up to 270 bar.
Benefits
- Internal pilot oil supply and internal pilot oil return, no additional fittings.
- 500 l/min nominal flow, maximum flow 1000 l/min, size 27.
- ±10 V command value on 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
- Spool symbol V1, 3 switching positions, spool position feedback in the electronics.
- NBR seals, ISO 4401-08-07-0-05 interface, 19.4 kg.
