DMN, Incorporated Hopper / Silo Pressure Relief Valve PRV

The PRV over-and-underpressu re relief valve is an indispensable component for guaranteeing atmospheric pressure in receiving and discharging vessels. The PRV is designed to avoid an explosion or implosion which can occur when an unacceptable level of pressure or vacuum arises inside the hopper or silo. In such a situation the PRV will automatically open and restore atmospheric conditions inside the silo or hopper. As soon as the atmospheric condition is achieved, the valve will close and re-establish sealing.
