10.7.1 Cleaning valve / replacing worn parts

Fig.44

Notice

The internal parts, consisting of the valve disk (15), stem (13),
double disk (16), the housing seat (15.1 and 16.1), the clamping
area (P) of the lantern and housing as well as the V-ring groove
and the O-ring groove (A) are precision areas.

Damage to these parts can result in malfunction.
► Handle the valve with care!

Notice
