4.1.2.10. Pressure Safety Valve
The safety valve (1) is an important protective
device. It limits the pressure in the silo tank
(operating pressure) to max 2 bar, thus pre-
venting the tank being exposed to excessive
pressure. The safety valve is mounted on the
air battery placed at the rear side of the ve-
hicle. The system pressure can be seen from
the manometer which is right at the inlet of the
valve.

4.1.2.11. Ventilation Valve
It is used to ventilate the silo vehicle. Close the
ventilation valve when the silo vehicle is requ-
ired to be unloaded with compressed air.
In normal status the ventilation
valve must be “open”, while pres-
surized discharging is performed
the ventilation valve should be
“closed”.
If the material is inhaled or comes
into contact with skin or eyes du-
ring venting, it can cause injuries
such as chemical irritation, burns and poi-
soning. Avoid physical contact with the
load. Avoid inhaling any dust that may es-
cape. Wear protective clothing that is app-
ropriate to the load. If the load causes an
injury, consult the material’s safety data
sheet for the remedial action that needs to
be taken.
