Pressure relief and vacuum system


The pressure relief and vacuum valve is a safety feature protecting the silo from damage incurred as a result of overpressure or vacuum, when large pressure or temperature fluctuations, fermentation, etc. might occur during filling or discharge. 

In such a case, the pressure relief and vacuum valve automatically opens and renews atmospheric conditions inside the silo or tank. As soon as the atmospheric conditions are reached, the valve closes.

The safety valve is installed directly onto the silo lid or using a weld flange which is a part of the valve.
