Applications
1.
Bleeding of a line where an air pocket has formed. This
application calls for installation at the top of the line.
2.
Bleeding of a tube on the suction side of a pump. The
suction side is bled automatically, before the pump starts,
establishing a vacuum. Binding of air to liquid will be
prevented, and so will subsequent cavitation. In this
application the valve is mounted in front of the pump, on
the top of the inlet tube.
Working Principle
The Dixon Sanitary air relief valve allows air to be removed
from a line or container without the liquid flowing out. Its
design does not allow air to enter the line or container, even
if subjected to a negative pressure. It is a double-seated
valve with a freely moving polypropylene ball. The ball, which
is lighter than water, closes against the upper or lower seat,
depending on the pressure conditions.
