A rotary table with large inertia depends on the fine resolution of the valve when it starts to move. The 4WRZE10W8-25-7X/6EG24N9EK31/A1V works there at 25 l/min rated flow, takes up to 315 bar and draws pilot oil internally while returning it externally.
Benefits
- 25 l/min rated flow, which gives fine resolution of the command signal at start.
- Spool symbol W8 blocks at centre, three switching positions, operating limit 315 bar.
- Internal pilot oil supply with external pilot oil return, without a pressure reducing valve.
- Command value 10 V bipolar into the on-board electronics, 24 VDC supply.
- Concealed manual override, 8.48 kg, size 10 to ISO 4401-05-05-0-05, FKM seals.
