Drives and long cables disturb a voltage signal, a current signal much less. This internally piloted size 16 valve takes 4...20 mA as its command value, releases 180 l/min nominal flow and holds 350 bar operating pressure.

In plants full of frequency converters a current command value is the safer choice. This pilot-operated size 16 valve handles 4...20 mA, routes its pilot oil internally and provides 180 l/min nominal flow.
Key benefits
- The 4...20 mA command input resists voltage picked up from converters and contactors.
- A broken wire shows up immediately as current below 4 mA, so the controller can react.
- 180 l/min nominal flow with 460 l/min maximum and 350 bar operating pressure.
- Pilot oil supplied and returned internally, leaving the manifold free of extra piping.
- Spool symbol W6, 12.2 kg, NBR seals, ISO 4401-07-07-0-05 connection pattern.

Applications
The valve is intended for feed and press axes in electrically noisy surroundings, for instance next to large drive cabinets. Diagnosis through the 4 mA live zero makes fault finding easier during operation. System pressure must stay above the minimum pilot pressure at all times.
