3.3 Operating principle
Under normal operation conditions there is no compressed air inside the valve body; allowing, thus, the owing
of the material inside the valve.
In the case of "stimulated” operation, compressed air is present inside the valve body and exerts pressure on
the sleeve, allowing the closing of the valve and, as a consequence, prevents the owing of the material.
