In electrically noisy halls, signal transmission is often the weakest link in the control chain. The 4WRZE32W6-520 therefore takes its command value as 4 to 20 mA and controls 520 l/min nominal flow in size 32 with it.
Benefits
- 4 to 20 mA command value, a broken line is visible in the signal.
- 520 l/min nominal flow, up to 1600 l/min throughput possible.
- 350 bar operating pressure with spool symbol W6 and three switching positions.
- External piloting without pressure reducing valve, connection diagram ISO 4401-10-09-0-05.
- 43.8 kg with UKCA evidence for EMC, 7-pole (6 + PE) connector to EN 175201-804.
