A zero point that shifts along with system pressure ruins every calibration. The 4WRZE32W6-520-7X/6EG24N9TK31/A1M therefore separates pilot oil supply from the main circuit and meters 520 l/min at 350 bar from a ±10 V command.
Benefits
- External pilot oil supply with internal return keeps pilot pressure constant without a second line to tank.
- 520 l/min nominal flow at 350 bar, body limit 1600 l/min.
- ±10 V command with electronics inside the valve, 24 V DC supply, 7-pole connector (6 + PE).
- W6 spool on ISO 4401-10-09-0-05 with four ports and three switching positions.
- 43.06 kg, NBR seals, HL hydraulic fluid, UKCA conformity.
