Silo Relief Valve

The combined pressure and vacuum relief valve is primarily designed to protect silos from damaging over and under pressures encountered during filling and emptying.
During pressure filling of silos, while addressing all problems associated with material build-up, weather ingress and flow path.
The application of a pressure relief valve is necessary to discharge possible pressure inside the silo, as well as vacuum pressure.
It is designed to open up at preset pressure and allow material to escape from the tank before damage can occur.
