Construction
The aeration and deaeration valve consists of a housing completeley welded and a float ball made of
stainless steel.
Function
In unfilled condition the float is in lower position and the deaeration valve is opened. When filling the
pressure vessel the air escapes. When the liquid rises in the deaeration housing, the ball floats and the
deaeration valve is closed. If air present during the operation process and thus descending of the ball, the
valve opens for a short time so that the air can escape
