− Put from the top the impact head shaft (S) into the guide (H) being careful not
to damage the gasket (P)
− Check the smooth sliding of the impact head shaft (S) into the guide (H)
Proceed with assembling of the homogenizing group:
− Insert the assembly guide and impact head into the homogenizing chamber
(B), from the top
− Assemble the flange (N) together with the pneumatic actuator (L) on the
homogenizing chamber (B)
− Tighten completely the nuts (M) in cross
− Connect the piping of the pneumatic control system
The above indications are valid for both homogenizing valves, on machines
