Control accuracy on large axes comes from spool position feedback. The 4WRTE32 uses it for a linear characteristic and carries 600 l/min nominal flow at 350 bar. Pilot oil is supplied and drained externally and the valve weighs 34.5 kg.

Total price
Without feedback on spool position a proportional valve drifts with temperature and contamination. The 4WRTE32E1-600L-4X measures that position internally and holds its linear characteristic, at 600 l/min nominal flow and 350 bar.
Benefits
- Internal piston position feedback for a repeatable, linear relation between command value and flow.
- 600 l/min nominal flow and up to 1600 l/min maximum flow in size 32.
- External pilot oil supply and external return for systems with their own control oil circuit.
- 4 to 20 mA command value through the on-board electronics on 24 V DC.
- 34.5 kg weight at 350 bar operating pressure, NBR seals and connection diagram ISO 4401-10-09-0-05.
