Excess Flow Valves are an additional feature to be used in combination with bursting discs to protect a refrigeration system from overpressure.

EXCESS FLOW VALVES

The use of excess flow valves is recommended in accordance with fact sheet AD2000 A1 and ASME Boiler & Pressure Vessel Code VIII Div.1 (paragraphs UG 125 through UG 137) when bursting discs or relief valves are being used in series or in combination. Excess flow valves keep the space between safety valve and bursting disc pressureless in case smaller leaks occur. They prevent the build-up of counter pressure. They work with a ball that gets pushed into its seat, if an overpressure occurs, e. g. when the bursting disc opens, thus preventing ventilation and enabling the safety valves to perform as intended. Furthermore pressure manometers and controllers can be connected

Transforming sidestreams into jet fuel

Transforming sidestreams into jet fuel

The aviation industry wants to use more sustainable aviation fuel, but supply is limited. To meet demand and secure cleaner air travel, suppliers need to unlock resources from existing sidestreams like fats and oils. How to scale up? That’s where GEA comes in.

In 1926, Ramesohl & Schmidt (later Westfalia Separator AG) launched their first bucket milking system. The Kirchhoff family was among the first to use it on their farm in Germany.

Do balde de ordenha ao robô: 100 anos de inovação agrícola na GEA

Há mais de 100 anos, a GEA vemk desenvolvendo tecnologias para a pecuária leiteira - desde as primeiras ordenhas de balde até os sistemas autônomos e conectados digitalmente. Essas inovações transformaram fundamentalmente a pecuária leiteira: longe das rotinas de trabalho intensivo, em direção a maior produtividade, bem-estar animal e operações diárias mais eficientes.
