Spool symbol V gives a straight characteristic curve, so every percent of signal adds the same amount of flow. That makes controller tuning easier. Size 10, 100 l/min nominal flow, 4...20 mA command value, operating pressure up to 350 bar.

A position controller is easier to tune when the valve curve keeps the same slope over the whole stroke. Spool symbol V delivers exactly that, and this size 10 valve puts it to work with 100 l/min nominal flow and a 4...20 mA current command value.
Benefits
- The linear V characteristic keeps loop gain constant across the full signal range.
- 100 l/min nominal flow at 350 bar, peak flow up to 300 l/min.
- 4...20 mA command value for plants with a remote controller and electrically noisy surroundings.
- External pilot oil supply with internal return needs only the additional X line.
- On-board electronics, CE conformity, weight 9.1 kg.

Applications
This version is used in closed position and force loops where the controller expects a known curve rather than having to linearise one itself. Examples are testing machines, infeed axes and calender gaps. The return through T assumes a tank line with low back pressure.
