The WAM® VCP Pressure Relief Valve is used to limit or control either an excess pressure or negative pressure imbalance when filling or emptying a silo. When preset pressure limits are exceeded, the spring-loaded lid is pushed up, so that excess pressure can escape or outside air can enter to bring internal/external pressure back into balance; then the pressure lid moves back into the "closed" position. VCP Pressure Relief Valves consist of a cylindrical housing with a bottom flange that is bolted to a flange ring which can be welded to the silo roof. VCP Valves are efficient, reliable, and provide final protection when unacceptable pressure issues endanger a silo structure.
