19 FITTING THE S VALVE
To protect the gaskets (Fig. 28 Ref. 1-2) before fitting the S valve
(Fig. 28 Ref. 3), fit the cone (Fig. 28 Ref. 4) to the toothed shaft
and then fit the valve itself.
Before refitting the mobile bearing race (Fig. 28 Ref. 5), extract
the cone (Fig. 28 Ref. 4) in the direction of the arrow and refit all
components to secure the S valve.

20 S VALVE REGISTRATION
The S valve requires registration if the distance between the disc
(Fig. 29 Ref. 1) and the wear plate (Fig. 29 Ref. 2) is greater than
0.25 mm or the S valve itself blocks repeatedly.
Incorrect registration of the valve results in a drop in pressure,
and hence the material flow during pumping is less than in normal
operation, while it may cause water leakage between the disc (Fig.
29 Ref. 1) and the wear plate (Fig. 29 Ref. 2) during washing.
The following procedures should be done with the ma-
chine SWITCHED OFF.
To register the S valve, proceed as follows:
- Remove the bracket (Fig. 30 Ref. 1) and then screw in the regis-
ter nut (Fig. 30 Ref. 2) to recover the backlash.
- Now fit the nut bracket again (Fig. 30 Ref. 1) with its bolts.
- Start the machine up at a low speed and check that the S valve is
switching properly.
