8.3 ADJUSTING THE S-VALVE
The S-valve should be adjusted to eliminate all play between the wear plate and the wear disc and make them seal to each
other. Play is caused by wear on the two elements produced by scraping.
Imperfect sealing can be detected during washing, when water seeps out from between the disc and the plate, and during
pumping, when slurry seeps out from between them.
As a rule, the S-valve should be adjusted when the distance between the disc and the wear plate is greater than about 0.25
mm or in case of frequent clogging of the S-valve.
The following steps must be carried out with the machine switched off.
- Remove the TE screw (FIG. 58-REF. 1), remove the lever locking the adjustment nut (FIG. 58-REF. 2) and loosen or tighten
the adjustment nut as required (FIG. 58-REF. 3); usually it is sufficient to turn the nut by 60°-120°.
- Put back the nut-locking lever (FIG. 58-REF. 2) and fasten it with the screw (FIG. 58-REF. 1).
