2.4.1 Safety valves
The
DUOMIX 230
is equipped with safety valves in the
air motors of the main pump (see Fig. 2), the flushing
pump and the feed pumps (if present).
The safety valves ensure that the max. permissible air
inlet pressure is not exceeded. If the air inlet pressure
exceeds the fixed limiting value at one of the points
mentioned above, the corresponding safety valve will
blow off.

WARNING
If the maximum permissible air inlet pressure is exceeded, components may
burst. This may result in damage to persons and property.
➤
Never allow the unit to run without or with defective safety valves!
➤
If a safety valve needs to be replaced, you can find the corresponding
order number on the machine card.
➤
When using new safety valves make sure that the valves have been set
to the max. permissible air inlet pressure of the
DUOMIX 230
as required
for the mixing ratio (see type plate or machine card) and sealed with a
lead seal.
Changing the mixing ratio may cause a change in pressure ratio and thus
require the adaptation of the max. permissible air inlet pressure of the main
pump. In this case you would have to replace the safety valve of the main
pump and the type plate – you should absolutely contact
WIWA
.
