Sanitary vacuum breaker valves are designed to prevent vacuum conditions from occurring in piping or storage tanks. These valves are typically installed at critical points throughout the handling system and allow atmospheric inflow to relieve vacuum conditions.Evacuating the tank may result in a pressure difference between the inside of the tank and the outside air, resulting in a downward force. This negative pressure can severely damage the tank and result in catastrophic damage to the equipment. When positive pressure is restored in the tank, the valve can be closed again to create a tight seal.
