Norit Südmo offers a line of spring-loaded ASME Pressure Relief Valves designed to protect sensitive processes against unacceptable overpressure without putting hygienic requirements at risk. If pressure exceeds the design pressure of the vessel, the Pressure Relief Valve will open, relieve the pressure, and immediately close. This ensures that the contents of the tank are not contaminated, and it does not require any downtime as the valve automatically resets. To ensure the highest level of hygienic operation, the valve seat can be lifted during CIP to ensure that all valve parts in contact with the vessel are cleaned and free of bacteria. The valves are designed and manufactured to the highest standards and meet ASME, FDA (3-A) and BPE requirements.
