8.2.1. Warnings

Always act slowly on valves and wait after each setting until the separation stabilizes
before doing another change.

When the desired regulation has been achieved, mark the position of each shutter.

To avoid butter oil or foam formation it’s necessary to work with higher pressures both in
buttermilk and in cream. Do not increase too much pressure values as this cause a reduction
in regulation sensibility.
Separator equipped with constant pressure valve

Rotate the pressure regulator of the bowl overflow RPT (fig. 7.2) until on MNT (fig. 7.2)
could be read a pressure of about 6 bar.

The regulation of counter-pressure at buttermilk outlet could be performed acting both on
shutter A and on regulator RPL. For the best regulation:
- act on regulator RPL in such a way that the pressure fall to zero;
- rotate shutter A until a pressure of 2,5

3 bar could be read;
- perform subsequent adjustings acting only on regulator RPL.

For a correct understanding of the regulation procedure reported below, at the words
“shutter A” should be substituted “regulator RPL”.
8.2.2. First setting
1) Feed the separator with water.
2) Partially open shutter B.
3) Gradually close shutter A until some water flow out of cream outlet.
4) The pressure read from the manometer is the minimum working pressure (MWP).
