In plants with long cable runs and frequency converters a current signal is the safe choice. This size 16 valve accepts a 4...20 mA command value, meters 150 l/min at 350 bar and makes a broken cable clearly distinguishable through the live zero.

A voltage command value loses meaning over 30 m of cable running next to a converter. This size 16 version therefore works with a 4...20 mA current command value and meters its 150 l/min nominal flow as steadily as it would on a short cable.
Benefits
- The 4...20 mA command value is immune to voltage drop and to interference picked up on long lines.
- Live zero at 4 mA separates a broken cable from a genuine zero command straight away.
- 150 l/min nominal flow at 350 bar, peak flow up to 460 l/min.
- Internal pilot oil supply with external pilot oil return, suited to tank lines carrying back pressure.
- Spool symbol E1, on-board electronics, weight 11.5 kg, interface ISO 4401-07-07-0-05.
