Large cylinders need flow without losing control quality. The 4WRKE in size 32 handles 400 l/min nominal flow and passes up to 1550 l/min at peak, at 350 bar. The 4 to 20 mA current command stays stable over long cable runs.

Total price
Once a cylinder is filled with several hundred litres per minute, control quality decides both cycle time and end position behaviour. The 4WRKE32W8-400P is built for that with 400 l/min nominal flow, up to 1550 l/min maximum flow and 350 bar operating pressure.
Benefits
- 400 l/min nominal flow and up to 1550 l/min peak flow in size 32.
- 350 bar operating pressure with FKM seals, rated for higher fluid temperatures than NBR.
- Linear characteristic with fine control range plus internal piston position feedback for high repeat accuracy.
- 4 to 20 mA current command through the on-board electronics, unaffected by voltage drop on long signal runs.
- 50 kg weight on connection diagram ISO 4401-10-09-0-05, with internal pilot oil supply and internal return.
